How long Voice Disorders studies take
Of 30 interventional studies with no phase under Voice Disorders, half reached primary completion within 37 months of starting, counting those still running.
| Start to primary completion | Every sponsor | Industry | Non-industry |
|---|---|---|---|
| Interventional, no phase | 37 mo8–48 · 30 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. How these figures are worked out
