How long Coronavirus Infections studies take

Of 107 phase 2 interventional studies under Coronavirus Infections, half reached primary completion within 9 months of starting, counting those still running.

Phase 1	10 mo3–18 · 61 studies	7 mo2–15 · 35 studies	15 mo8–19 · 26 studies

Observational	14 mo5–26 · 245 studies	—	15 mo5–28 · 228 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.
