Troponin Level | Odds Ratio | 95% CI | P Value | AUC | 95% CI |
---|---|---|---|---|---|
Initial troponin | 1.074 | 1.063-1.086 | <0.0001 | 0.8562 | 0.8454-0.8670 |
Maximum troponin | 1.031 | 1.028-1.034 | <0.0001 | 0.9401 | 0.9353-0.9449 |
Change in troponin (maximum – minimum) | 1.031 | 1.027-1.034 | <0.0001 | 0.8939 | 0.8848-0.9030 |
Note: Logistic regression with the Firth penalized likelihood approach was performed to assess the predictive ability of initial, maximum, and the change in troponin level on a primary diagnosis of acute myocardial infarction vs any other diagnosis. The P value for troponin value indicates statistical significance for predicting acute myocardial infarction.
AUC, area under the receiver operating characteristic curve.
