How long Fever studies take

Of 16 phase 4 interventional studies under Fever, half reached primary completion within 17 months of starting, counting those still running.

Start to primary completion	Every sponsor	Industry	Non-industry
Phase 4	17 mo11–42 · 16 studies	—	—
Interventional, no phase	16 mo6–30 · 74 studies	—	17 mo7–30 · 66 studies
Observational	22 mo8–36 · 61 studies	—	22 mo8–47 · 51 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.
