How long Risk Reduction Behavior studies take

Of 169 interventional studies with no phase under Risk Reduction Behavior, half reached primary completion within 25 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase25 mo13–46 · 169 studies—25 mo13–42 · 167 studies
Observational20 mo17–… · 19 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.
