How long Hyperoxia studies take

Of 39 interventional studies with no phase under Hyperoxia, half reached primary completion within 12 months of starting, counting those still running.

Observational20 mo12–25 · 16 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.
