Logistic Regression With the Firth Penalized Likelihood Approach for Initial, Maximum, and Change in Troponin on Acute Myocardial Infarction

Troponin LevelOdds Ratio95% CIP ValueAUC95% CI
Initial troponin1.0741.063-1.086<0.00010.85620.8454-0.8670
Maximum troponin1.0311.028-1.034<0.00010.94010.9353-0.9449
Change in troponin (maximum – minimum)1.0311.027-1.034<0.00010.89390.8848-0.9030
  • 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.
