How long Acute Coronary Syndrome studies take

Of 92 phase 4 interventional studies under Acute Coronary Syndrome, half reached primary completion within 42 months of starting, counting those still running.

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.
