Data for each participant in a trial. This contrasts with aggregate or summary data, which is produced by combining data from multiple participants. Individual participant data allows for the replication of all analyses in study reports and exploration of further analyses. IPD generally come in two forms: electronic datasets (that are therefore readily analyzable with software packages) and printed/paper listings (as in the type found in the sections of CSRs that contain individual listings).
Also called Individual Patient Data and IPD.
