How long Hyperkalemia studies take

Of 18 phase 3 interventional studies under Hyperkalemia, half reached primary completion within 16 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 316 mo11–29 · 18 studies——
Phase 424 mo23–44 · 16 studies——
Interventional, no phase25 mo8–28 · 16 studies——
Observational16 mo8–27 · 20 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.
