How long Impulsive Behavior studies take

Of 55 interventional studies with no phase under Impulsive Behavior, half reached primary completion within 26 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase26 mo13–34 · 55 studies—26 mo13–34 · 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.
