How long Dyspnea studies take

Of 23 phase 2 interventional studies under Dyspnea, half reached primary completion within 41 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 241 mo18–77 · 23 studies——

Observational24 mo11–46 · 125 studies—26 mo11–47 · 116 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.
