Availability of Individual Participant Data of clinical trials


Sharing of clinical trial data to improve transparency and enable data re-analysis is on the rise globally. Individual participant data (IPD) meta-analysis offers an enhanced scope of in-depth analysis, including but not limited to understand how participant-level covariates might affect treatment effects. A key challenge for evidence synthesis specialists conducting IPD meta-analysis is the availability of de-identified participant-level data from clinical trials.


  1. To examine how information on individual participant data availability is captured in different clinical trial registries
  2. To analyse the intent of individual participant data sharing in records from clinical trial registries

Research Methodology

We will search for and analyse data related to individual participant data availability in clinical trial registries.

Potential Impact

The results of the meta-research project will offer information to inform policies to inform the availability of individual participant data
