How long Contraception Behavior studies take

Of 64 interventional studies with no phase under Contraception Behavior, half reached primary completion within 20 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase20 mo13–40 · 64 studies—20 mo13–40 · 64 studies
Observational17 mo14–22 · 11 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.
