Troponin Level | Odds Ratio | 95% CI | P Value | AUC | 95% CI |
---|---|---|---|---|---|

Initial troponin | 1.009 | 1.004-1.013 | 0.0002 | 0.6547 | 0.6334-0.6760 |

Maximum troponin | 1.007 | 1.005-1.009 | <0.0001 | 0.6782 | 0.6576-0.6989 |

Change in troponin (maximum – minimum) | 1.007 | 1.005-1.009 | <0.0001 | 0.6113 | 0.5892-0.6333 |

Note: Logistic regression with the Firth penalized likelihood approach was performed to assess the predictive ability of initial, maximum, and change in troponin level on death at index admission. The
