quality and efficiency of clinical trials.
Using publicly available and downloadable data from ClinicalTrials.gov, a restructured and reformatted relational database was developed. This is referred to as the database for Aggregate Analysis of ClincalTrials.gov (AACT). The purpose of AACT is to make the acquisition and analysis of the aggregate data from ClinicalTrials.gov more user-friendly. CLICK HERE for an overview of the background on ClinicalTrials.gov and the AACT database.
The AACT database extracts are available for download in three formats. Please refer to the supporting documents below for more information about how to use AACT.
ZIP files containing these database extracts may be downloaded from the links provided below:
*This dataset reflects data downloaded from ClinicalTrials.gov March 27, 2015.
**The Readme file (located in each ZIP file) provides critical considerations for database administrators and statistical programmers regarding importing the database extracts.
***Note: This version of AACT does not include 2 tables that are normally part of the release: CONDITION_BROWSE and INTERVENTION_BROWSE. MeSH terms in these table are generated by an NLM algorithm which periodically changes. This information was incomplete at the time of the March, 2015 extract from clinicaltrials.gov, so has been omitted from this release.
The Points to Consider Document 2015_March provides guidelines for investigators to consider when planning a statistical analysis of the ClinicalTrials.gov database. It is not intended to be a comprehensive guide. See document for information on:
