How long Patient Compliance studies take

Of 15 phase 4 interventional studies under Patient Compliance, half reached primary completion within 35 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 435 mo27–65 · 15 studies——
Interventional, no phase20 mo9–38 · 237 studies—20 mo9–38 · 224 studies
Observational23 mo10–37 · 65 studies—25 mo10–37 · 55 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.
