| ACS HR (95% CI) | Non-ACS HR (95% CI) | Interaction P Value* | |
|---|---|---|---|
| Cardiovascular death/MI/DLI | 1.08 (1.03 to 1.12)† | 1.01 (0.96 to 1.06) | 0.04 |
| Cardiovascular death/MI | 1.05 (0.998 to 1.11) | 0.98 (0.92 to 1.05) | 0.14 |
| MI/DLI | 1.09 (1.04 to 1.14)† | 1.00 (0.95 to 1.05) | 0.01 |
| DLF | 1.12 (1.06 to 1.18)† | 1.00 (0.95 to 1.06) | 0.004 |
| Cardiovascular death | 1.04 (0.95 to 1.14) | 0.98 (0.82 to 1.17) | 0.57 |
| MI | 1.07 (1.00 to 1.14)† | 0.97 (0.90 to 1.04) | 0.05 |
| MI lesion | 1.12 (0.996 to 1.26) | 0.91 (0.79 to 1.04) | 0.02 |

ACS indicates acute coronary syndrome; DLF, deferred lesion failure; DLI, deferred lesion intervention; FFR, fractional flow reserve; HR, hazard ratios; MI, myocardial infarction.
