Missing actual dates and counts mark one of the quietest structural zones in older CT.gov studies

Closed studies missing actual primary completion, completion, or enrollment fields remain dramatically quieter than studies with those fields properly recorded, and suspended studies are worst on discipline.

Actual-field flags turn vague metadata quality into a direct hiddenness signal with near-perfect separation.

All three actual-field flags show an extreme split between present and missing groups.
That separation is much sharper than many of the softer structural gradients elsewhere in the series.

Missing actual primary completion produces one of the highest ghost-protocol rates in the atlas.
The ghost view shows that this is not merely a missing-results artifact.

STATUS AND DISCIPLINESelected status-specific missing-actual ratesCompleted | primary0.0%Withdrawn | primary58.1%Suspended | primary76.4%Completed | completion2.1%Withdrawn | completion59.5%Suspended | completion100.0%
Suspended and withdrawn studies are the weakest on actual-field discipline, especially for completion fields.
This ties the actual-field project back to the stopped-trial disclosure story rather than leaving it as an isolated metadata page.
Read Across Projects

Across The Series

Each project isolates a different dimension of registry opacity, but the point is the contrast between them, not a single leaderboard.

Industry
CT.gov Industry Disclosure Gap

Industry-focused missing-results stock, sponsor backlogs, and structural sparsity inside CT.gov.

Sponsor Classes
CT.gov Sponsor-Class Hiddenness

Sponsor-class comparisons on rate, stock, and structural hiddenness rather than one flattened ranking.

Phases
CT.gov Phase Reporting Gap

Phase-by-phase disclosure gaps showing how silence changes along the development pathway.

Structural
CT.gov Structural Missingness

Field-level missingness across publication links, IPD statements, descriptions, and locations.

Visibility
CT.gov Evidence Visibility Gap

Results-plus-publication visibility states showing how many older trials are fully visible, partly visible, or ghosted.

Cohorts
CT.gov Completion Cohort Debt

Completion-era reporting debt showing how older eligible cohorts drift on no-results and ghost-protocol rates.

Conditions
CT.gov Condition Hiddenness Map

Keyword-classified therapeutic-area hiddenness mapping across common condition families.

Concentration
CT.gov Sponsor Backlog Concentration

Concentration and inequality analysis showing how much unresolved stock sits inside a thin sponsor slice.

Rule Eras
CT.gov Rule-Era Reporting Gap

Policy-era comparisons across pre-FDAAA, FDAAA, and later CT.gov completion cohorts.

PubMed Audit
CT.gov Publication Undercount Audit

Sample-based external PubMed NCT audit testing how often CT.gov no-link records hide an external paper trail.

Oncology
CT.gov Oncology Hiddenness

Oncology-specific CT.gov hiddenness showing where cancer-trial stock, phases, and sponsors still go quiet.

Cardiovascular
CT.gov Cardiovascular Hiddenness

Cardiovascular CT.gov hiddenness showing how heart and vascular studies remain quiet across major phases and sponsors.

Metabolic
CT.gov Metabolic Hiddenness

Metabolic CT.gov hiddenness across obesity, diabetes, and related trial portfolios with large late-phase and NA stock.

Size
CT.gov Enrollment-Size Gap

Enrollment-size gradients showing how older small trials remain much quieter than larger registered studies.

Geography
CT.gov Geography-Scale Visibility

Site and country footprint analysis showing how larger trial geographies map onto much better public visibility.

Purpose
CT.gov Design-Purpose Hiddenness

Primary-purpose and allocation analysis showing which trial intents remain most obscured on CT.gov.

Delay
CT.gov Completion-Delay Debt

Registration-to-completion delay analysis showing short-cycle studies carry the heaviest reporting debt.

Architecture
CT.gov Trial-Architecture Gap

Arm-count and intervention-count analysis showing simpler trial architectures are often the quietest.

Interventions
CT.gov Intervention-Type Gap

Intervention-family analysis showing which declared treatment modalities remain quietest on older CT.gov records.

Countries
CT.gov Country Reporting Map

Named-country visibility analysis showing large geographic divides in older CT.gov reporting debt.

Stopped
CT.gov Stopped-Trial Disclosure Gap

Final-status analysis showing how withdrawn, suspended, and terminated studies remain structurally quieter than completed trials.

Outcomes
CT.gov Outcome-Density Gap

Outcome-count and outcome-description analysis showing sparse protocols are often the quietest CT.gov segment.
