How the Mathematica Policy Research archive is shaped

29 indexed studies, none listed as recruiting (0% open); 26 completed (90%).

Phase labels are sparse on this sponsor index, so phase mix is not charted here.

Top condition: Head Start Participation (3 trials), 9 others listed.

How to read a closed sponsor archive

When recruiting_count is zero, the indexed set is completed or otherwise not open. Phase tilt still describes where archived studies sat on the investigational pathway. Re-check ClinicalTrials.gov before acting.

Mathematica Policy Research: archived-pipeline peers nationwide
