What this object claims to contain

not recorded on the page this object was built from

Not held in this object. No screening log is recorded for this review. The included set was reconciled against published syntheses rather than screened from a search, so no records-identified, excluded-with-reason or dual-screening counts exist.

Extracted values, and where each came from

One row per extracted value. Every row carries the value, the verbatim sentence it was read from, a resolvable link to the source, and whether the number was read or derived. Where any of those is absent the row says so rather than omitting the value.

Pooled result

Estimate withdrawn. The four trials do not share one endpoint, and two of them differ from the others in ways the registry states explicitly. VOYAGER pad's primary carries two whole components that appear in no other trial here. Verbatim: 'Composite of Myocardial Infarction (MI), Ischemic Stroke, Cardiovascular Death, acute limb ischemia (ALI) and major amputation due to a vascular etiology' -- five components. COMPASS's is 'Myocardial Infarction (MI), Stroke, or Cardiovascular (CV) Death' and ATLAS ACS 2's is 'Cardiovascular Death, Myocardial Infarction, or Stroke': three each, with no limb outcome at all. Acute limb ischaemia and major amputation are not rare in a post-revascularisation peripheral-artery population; they are much of what that trial was counting. And COMMANDER hf counts a different death. Its registered primary is 'Event Rate of all-cause mortality, Myocardial Infarction (MI), or Stroke'. COMPASS and ATLAS count cardiovascular death. All-cause mortality in a decompensated-heart-failure population includes a great many deaths an antithrombotic cannot prevent, and pooling it with a cardiovascular-death composite averages two different questions. COMMANDER hf also registers a rate rather than a count: 'Event Rate / (100 pt-yr) = 100*n/(total risk exposure)'. That is why this page holds no event counts for it, and none for ATLAS ACS 2, whose primary is registered as a percentage of patients analysed while on treatment. Separately: the populations are not one population -- stable coronary or peripheral artery disease; peripheral artery disease immediately after lower-extremity revascularisation; heart failure with coronary disease after decompensation; and recent acute coronary syndrome. That alone would not withdraw an estimate, and it is recorded because it is the reason the endpoints differ.

What is confirmed, stated as prominently as what is wrong. (1) the arithmetic is right. Pooling the four published hazard ratios by DerSimonian-Laird gives 0.8494 (0.7775 to 0.9278), which is the card's 0.85 (0.77 to 0.94) to within rounding. Nothing here was miscomputed; what was averaged should not have been. (2) the trial identities are correct and every arm size matches its registration. (3) the direction is consistent across all four, and that is worth saying plainly because a withdrawal should not leave a reader with less than they had. COMPASS 0.76 (0.66 to 0.86), VOYAGER PAD 0.85 (0.76 to 0.96), ATLAS ACS 2 0.84 (0.72 to 0.97) and COMMANDER hf 0.94 (0.84 to 1.05). Three of the four exclude no effect; all four point the same way. Every one is on this page. What this withdrawal does not establish: not that rivaroxaban is ineffective in vascular disease, and not that no synthesis of these trials is possible. It establishes that these four endpoints are not one endpoint, so a single pooled hazard ratio over them does not estimate a quantity any of the four trials measured. A note on the published comparison, per this repository's own queue item 17: the benchmark database's only entry for this outcome is COMPASS itself, Eikelboom 2017, HR 0.76 (0.66 to 0.86) -- and COMPASS is one of the included trials. A benchmark that shares a registration with an included trial is not an independent comparison. Here it at least does not agree with the pooled value, so nothing was falsely corroborated; on BEMPEDOIC_ACID the same configuration produced perfect agreement with itself. The replacement question is identified and deliberately not taken: the three trials whose composites genuinely share components -- COMPASS, ATLAS ACS 2 and, if its all-cause death component is accepted, COMMANDER hf -- could be synthesised without VOYAGER's limb outcomes. Choosing which of those is an estimand decision, and its answer is computable from the values already on this page. Parked.

Changing the range moves the axis window only. The guides stay labelled with the null and the extremes of the plotted intervals, so no plotted value and no printed number differs between these views — and that is checked at build time, not asserted. Ranges not offered because they would crop the data: 0.7 to 1.3.

Risk of bias

⬇ SVG (vector) 1 KB

Only the vector format is offered for this figure, by choice: it is line art — discrete marks, glyphs and labels — which SVG reproduces exactly at any size, so a raster would add weight without adding fidelity. The build was able to rasterise; it was asked not to.

Not drawn, because there is nothing to draw it from.

GOSH

Deliberately not drawn. Every subset meta-analysis of 4 trials is 15 points; a cloud that small cannot show the multimodality GOSH exists to reveal, and a reader would take the picture as evidence of its absence.

TSA boundaries depend entirely on a target information size that must be pre-specified. This review's protocol registers none, so any boundary drawn here would be a parameter chosen after seeing the data -- which is the practice TSA exists to protect against.

  1. The pooled estimate for this outcome has been WITHDRAWN, so there is no estimate for a certainty rating to be about. Any rating this object still carries for this outcome was made about the withdrawn estimate and is not shown beside it.
  2. Read this beside `whether the estimand was established`. That flag records that every contributing trial measures the same quantity. It records nothing about what that quantity was measured against -- whether the comparators are of one kind, whether each comparison was randomised, whether it was concurrent. The two questions were never separated. Named as P48 in PAGE-STANDARD.md v1.21.0 and swept by scripts/audit_mixed_contrast_pools.py.

Introduction

Background. This review asks: Does adding low-dose rivaroxaban to antiplatelet therapy reduce major vascular events? Four trials ask versions of this and their registered primary endpoints are not the same endpoint. It examines 4 randomised trials and does not pool them, against aspirin alone or placebo, depending on the trial. The outcome sought is Major vascular events, as each trial defines them.1

Results

Major vascular events, as each trial defines them. These 4 trials are not pooled, and the reason is stated rather than the outcome being quietly omitted: The four trials do not share one endpoint, and two of them differ from the others in ways the registry states explicitly. Voyager pad's primary carries two whole components that appear in no other trial here. Verbatim: 'Composite of Myocardial Infarction (MI), Ischemic Stroke, Cardiovascular Death, acute limb ischemia (ALI) and major amputation due to a vascular etiology' -- five components. Compass's is 'Myocardial Infarction (MI), Stroke, or Cardiovascular (CV) Death' and atlas acs 2's is 'Cardiovascular Death, Myocardial Infarction, or Stroke': three each, with no limb outcome at all. Acute limb ischaemia and major amputation are not rare in a post-revascularisation peripheral-artery population; they are much of what that trial was counting. And commander hf counts a different death. Its registered primary is 'Event Rate of all-cause mortality, Myocardial Infarction (MI), or Stroke'. Compass and atlas count cardiovascular death. All-cause mortality in a decompensated-heart-failure population includes a great many deaths an antithrombotic cannot prevent, and pooling it with a cardiovascular-death composite averages two different questions. Commander hf also registers a rate rather than a count: 'Event Rate / (100 pt-yr) = 100*n/(total risk exposure)'. That is why this page holds no event counts for it, and none for atlas acs 2, whose primary is registered as a percentage of patients analysed while on treatment. Separately: the populations are not one population -- stable coronary or peripheral artery disease; peripheral artery disease immediately after lower-extremity revascularisation; heart failure with coronary disease after decompensation; and recent acute coronary syndrome. That alone would not withdraw an estimate, and it is recorded because it is the reason the endpoints differ.1

Limitations

Eligible trials that do not contribute: All four included registrations contribute a value to this review; none was dropped.1

This review does not claim that the per-trial hazard ratios were checked against the trials' own results records; they are the page's embedded values.2

1 claim(s) previously made about this review were corrected and the corrections are retained on the object rather than overwritten.3

What this review does not give a clinician: the number of events in each arm, any absolute effect or number needed to treat and any measure of harm. A relative effect cannot be turned into the benefit or the risk facing one patient without them, so this review can support a judgement about what these trials found and not a judgement about what to do.4

Notes on this record — sections not written, and why

Of the four properties this project requires of a completed topic, 0 are held (none) and 4 are refused with the obstacle named in the evidence (the number of published syntheses this review was a GRADE certainty rating for each pooled outcome, the statistical model's output, quoted as it was produced, a risk-of-bias judgement for each reported result).1

Not reported in this record

The items below were not written because the record does not hold what they would be composed from. They are named here so that an absence is not mistaken for an omission.

Items not reported, and why
Article areaItem not reportedReason
AbstractThe Background sentence of the abstractBackground is argument -- why this question matters -- and no arrangement of the quantities this object holds yields it. It is emitted only from an authored field and there is no composition path for it here
AbstractThe Methods sentence of the abstractNone of the method facts this would be composed from -- databases searched, eligibility, pooling model, risk-of-bias tool, certainty approach -- is recorded on this object
AbstractThe Results sentence of the abstract -- no outcome on this object carries a pooled point estimate, so there is nothing to report and none is manufactured hereThe reason each pool is declined is given in Results
AbstractThe Conclusions sentence of the abstractA conclusion is argument -- what a reader should now believe -- and it is emitted only from an authored field. Composing one from the estimate would be this renderer telling the reader what to conclude, which no field supports
KeywordsThe keyword listA content gap; no keywords are recorded and inventing them would be indexing this review under terms nobody chose
Methods — searchA database search for primary trials, which was not carried out for this review; the included trials were identified from named registrationsNo further reason is recorded.
Methods — how many studies at each stageThe k cascadeNo further reason is recorded.
Methods — synthesisThe model/estimator sentence for major vascular events, as each trial defines themNo pooled estimate was produced for this outcome, so no model was fitted and none is described
Methods — synthesisThe claim that records were screened in duplicate by two independent reviewersNo further reason is recorded.
Methods — synthesisThe claim that risk of bias was assessed with a named toolNo further reason is recorded.
Methods — synthesisThe claim that certainty of evidence was gradedNo further reason is recorded.
Methods — synthesisThe claim that the review methods were prespecified before data collectionNo further reason is recorded.
Risk of bias in the included resultsThe risk-of-bias assessmentNo further reason is recorded.
Risk of bias in the included resultsThe risk-of-bias distributionNo further reason is recorded.
Certainty of the evidenceCertainty of the evidence, by outcome, with every rating stepNo further reason is recorded.
Certainty of the evidenceThe certainty assessmentNo GRADE record is held, so the certainty column elsewhere on this page is an em dash rather than a guess
DiscussionThe Discussion -- this is a content gapThe object records no interpretive text, and none is generated here: text written by the renderer would be an argument no field supports
Comparison with published synthesesThe comparison with published synthesesNo published synthesis is recorded for this topic, so no denominator can be given
ConclusionsThe Conclusions -- this is a content gapThe object records no interpretive text, and none is generated here: text written by the renderer would be an argument no field supports
Data availabilityThe data availability statementNo further reason is recorded.
Software availabilityThe software and environment statementNo further reason is recorded.
Author contributionsThe author-contributions statementWho did what is a fact about people, and this object records none
Competing interestsThe competing-interests declarationF1000Research requires this section on every article, and requires explicit text where there is nothing to declare. It is a statement about the author and not about the evidence: no field of this object implies it and none is invented here
Grant informationThe grant informationThe venue requires each funder's name, the grant number where applicable, and the person the grant was assigned . None of that is derivable from a synthesis
Funding and conflicts of interestThe funding and conflict-of-interest statement -- a content gapA submission requires it and this object does not carry it; it is not inferable from anything held here
Note on registrationThe registration noteNo further reason is recorded.
RegistrationA registration statement: no prospective registration is recorded for this review, and whether one exists elsewhere has not been establishedNo further reason is recorded.
Extended data: statistical output, quoted verbatimThe verbatim model outputNo analysis output is stored on this object, so nothing can be quoted and nothing is paraphrased in its place
Submission conformanceThe submission conformance statementNo further reason is recorded.
Notes on this record — sections not written, and whyThe list of refused propertiesNo further reason is recorded.

Page standard

UNSTAMPED — unknown-version. This page carries no build_stamp, so the standard it was built to cannot be established. That is a statement about the record, not a claim that the page is below standard.

Every number on this page is projected from a single canonical object, and each measured cell names the source analysis it was read from. That is what is machine-checked. It does not establish that the underlying sources are right, only that this page faithfully reports them.
