How long Deglutition Disorders studies take

Of 297 interventional studies with no phase under Deglutition Disorders, half reached primary completion within 21 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase21 mo10–38 · 297 studies—21 mo10–39 · 288 studies
Observational25 mo11–49 · 120 studies—25 mo11–52 · 117 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.
