Who these studies take
Of the 22 Ventricular Fibrillation studies recruiting now, 19 (86%) set no upper age limit and 0 (0%) stop at 75 or younger. 2 (9%) take children under 18. 0 (0%) are for women only and 0 (0%) for men only; 4 (18%) take healthy volunteers.
| Age | Women | Men |
|---|---|---|
| 10 | 2 (9%) | 2 (9%) |

| 85 | 19 (86%) | 19 (86%) |
Across all 186 studies, recruiting or not: 9% stop at 75 or younger and 1% at 65; 12% take children; 0% are for women only and 1% for men only; 5% take healthy volunteers. From each study’s registry entry; the criteria on its page decide.
How long Ventricular Fibrillation studies take
Of 28 interventional studies with no phase under Ventricular Fibrillation, half reached primary completion within 38 months of starting, counting those still running.
| Start to primary completion | Every sponsor | Industry | Non-industry |
|---|---|---|---|
| Interventional, no phase | 38 mo9–53 · 28 studies | — | — |
| Observational | 74 mo39–… · 28 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
