How long Generalized Anxiety Disorder studies take

Of 183 interventional studies with no phase under Generalized Anxiety Disorder, half reached primary completion within 28 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase28 mo15–53 · 183 studies—29 mo16–55 · 174 studies
Observational17 mo9–56 · 24 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.
