How long Dysmenorrhea studies take

Of 17 phase 3 interventional studies under Dysmenorrhea, half reached primary completion within 28 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 328 mo19–30 · 17 studies——
Interventional, no phase8 mo3–16 · 188 studies—8 mo4–16 · 178 studies
Observational23 mo4–47 · 22 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.
