|---|---|---|---|---|---|
| Any bleeding | IABP use | −2.69 | −4.29 to −1.11 | 20.89 | 23.58 |
| Procedure-related bleeding | IABP use | −2.13 | −3.53 to −0.66 | 22.40 | 24.54 |

a
Reference, cardiac stratum.
b
Reference, no intra-aortic balloon pumping (IABP) group. ΔRestricted mean survival time (RMST) = RMST (Comparison) – RMST (Reference). Positive values indicate longer mean event-free survival in the comparison group.
