How long Pneumonia studies take

Of 67 phase 3 interventional studies under Pneumonia, half reached primary completion within 19 months of starting, counting those still running.

Start to primary completion	Every sponsor	Industry	Non-industry
Phase 1	12 mo6–34 · 35 studies	—	—
Phase 2	14 mo7–28 · 64 studies	—	11 mo6–28 · 39 studies
Phase 3	19 mo8–41 · 67 studies	—	26 mo9–57 · 41 studies
Phase 4	31 mo21–40 · 49 studies	—	33 mo21–43 · 42 studies
Interventional, no phase	21 mo10–31 · 265 studies	—	21 mo11–31 · 258 studies
Observational	27 mo13–53 · 223 studies	—	27 mo14–57 · 210 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.
