How long Venous Thrombosis studies take

Of 34 phase 3 interventional studies under Venous Thrombosis, half reached primary completion within 44 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 219 mo12–42 · 16 studies——

Observational46 mo21–82 · 127 studies—47 mo21–99 · 103 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.
