How long Pre-Eclampsia studies take

Of 35 phase 4 interventional studies under Pre-Eclampsia, half reached primary completion within 29 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 125 mo11–34 · 20 studies——
Phase 429 mo17–35 · 35 studies——
Interventional, no phase24 mo9–43 · 176 studies—24 mo9–43 · 171 studies
Observational30 mo11–56 · 200 studies—27 mo11–56 · 191 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.
