How long Venous Insufficiency studies take

Of 46 interventional studies with no phase under Venous Insufficiency, half reached primary completion within 15 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase15 mo9–38 · 46 studies—14 mo9–60 · 37 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.
