How long Respiration Disorders studies take

Of 17 phase 1 interventional studies under Respiration Disorders, half reached primary completion within 13 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 113 mo6–19 · 17 studies——
Phase 226 mo16–33 · 12 studies——
Interventional, no phase18 mo7–35 · 111 studies—18 mo7–37 · 91 studies
Observational26 mo10–55 · 75 studies—32 mo14–60 · 60 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.
