How long Anorexia Nervosa studies take

Of 151 interventional studies with no phase under Anorexia Nervosa, half reached primary completion within 43 months of starting, counting those still running.

Start to primary completion	Every sponsor	Industry	Non-industry
Interventional, no phase	43 mo24–63 · 151 studies	—	43 mo24–63 · 151 studies
Observational	38 mo16–72 · 56 studies	—	38 mo16–72 · 56 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.
