How long Bradycardia studies take

Of 83 interventional studies with no phase under Bradycardia, half reached primary completion within 21 months of starting, counting those still running.

Observational42 mo18–96 · 73 studies34 mo17–79 · 35 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.
