Authors propose three-tier framework for clinical trial data transparency
A BMC Medicine article proposes matching clinical-trial data access to the scientific work researchers seek to reproduce or undertake. Its framework distinguishes publication-time reduced datasets, reproducibility packages and governed access to broader individual participant data (IPD).
- Framework links data access to intended scientific use.
- Three tiers range from reduced datasets to governed IPD access.
- Publication-time datasets are proposed as a practical transparency floor.
The authors argue that clinical-trial data transparency should be assessed according to what a particular data release allows researchers to do. They propose three tiers: publication-time reduced datasets (Tier 1), which support numerical reproduction of endpoints and analyses based on the released observations; reproducibility packages (Tier 2), which add analysis-ready data, code, derivation logic and documentation to reproduce the reported analytic process; and governed access to broader de-identified IPD (Tier 3), enabling new analyses and reassessment of operational and analytic decisions.
The framework treats reconstructed pseudo-IPD derived from published Kaplan–Meier curves separately, because these data are not released from the trial database. The authors propose publication-time reduced datasets as a practical minimum for timely transparency when broader IPD are not yet accessible, while emphasising that endpoint-level reproducibility is not equivalent to reproducing the full analysis or enabling broader reuse. This is a conceptual proposal, not an empirical evaluation of the framework; privacy, governance and data-processing arrangements remain relevant across all tiers.
