Named-country involvement exposes large geographic divides in older CT.gov reporting debt

The United States dominates the stock, but named-country rates diverge sharply: Egypt and China remain very quiet, while Poland, Australia, and Japan look much cleaner.

Once named countries are plotted directly, the registry looks geographically stratified rather than generically multinational.

The biggest named-country stocks are not converging on one common reporting level.
This chart focuses on scale first so the country story does not overfit to tiny country tails.
Selected country contrast
SELECTED LARGE COUNTRIESSelected named-country contrast on the 2-year no-results metricUnited States52.1%Egypt95.8%China81.7%Poland33.5%Australia43.4%Japan40.5%
Egypt and China remain far quieter than the cleaner Poland, Australia, and Japan profiles.
The selected-country panel makes the geographic divide easier to read than a longer ranked table.
Ghost protocols
COUNTRY GHOSTSGhost-protocol rate across selected named-country footprintsUnited States33.6%Egypt63.4%China47.6%Poland17.1%Australia24.5%Japan24.5%
The same divide survives on the stricter ghost-protocol metric.
That matters because it reduces the chance that the country contrast is only a publication-link artifact.
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.

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.

Actual Fields
CT.gov Actual-Field Discipline

Closed-study actual-field analysis showing missing actual dates and counts are a strong warning sign for opacity.
