Project
This project shifts the focus from missing results to missing descriptive context, and the GitHub Pages root now exposes that structure directly instead of burying it in a subfolder.
Results reporting is only one layer of hiddenness. Publication links and IPD statements disappear at scale too.
A standalone E156 project on the descriptive fields that disappear from ClinicalTrials.gov even before results reporting is considered.
Across The Series
The split projects are meant to be read together: one for industry, one for sponsor classes, one for phases, and one for structural missingness.
A standalone E156 project on how much long-past non-disclosure and structural sparsity remain inside industry-linked ClinicalTrials.gov records.
A standalone E156 project comparing sponsor classes on rate, stock, and structural sparsity rather than flattening everything into one leaderboard.
A standalone E156 project on how reporting gaps change by trial phase, showing that phase structure matters alongside sponsor class.
