Fig. 1: Classification of stopped reasons for 28,561 clinical trials in ClinicalTrials.gov.
From: Genetic factors associated with reasons for clinical trial stoppage
Predicted trial stop reasons are shown in rows with counts of trials per start year, clinical phase or therapeutic area shown by the color in each cell. The outcome groupings of the stopped reasons are shown using the color next to the stopped reason label. Note that trials start potentially many years before they are stopped.
