How long Learning Disabilities studies take

Of 99 interventional studies with no phase under Learning Disabilities, half reached primary completion within 29 months of starting, counting those still running.

Start to primary completion	Every sponsor	Industry	Non-industry
Interventional, no phase	29 mo9–51 · 99 studies	—	30 mo9–53 · 96 studies
Observational	110 mo12–150 · 34 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.
