Start to primary completionEvery sponsorIndustryNon-industry
Phase 160 mo45–95 · 16 studies——
Phase 2111 mo64–149 · 22 studies——

Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study.
