NRI and IDI for evaluating improvement to predict SIMD after adding biomarkers to h-FABP
Logarithm of the variable | NRI (%) | P value for NRI | IDI (%) | P value for IDI |
ln h-FABP+ln MPO+ln cTnI | 18.7 | 0.025 | 3.3 | 0.033 |
ln h-FABP+ln MPO | 9.2 | 0.212 | 1.8 | 0.108 |
ln h-FABP+ln cTnI | 9.5 | 0.103 | 0.8 | 0.353 |
NRI: net reclassification improvement; IDI: integrated discrimination improvement; SIMD: sepsis-induced myocardial dysfunction; h-FABP: heart-type fatty acid-binding protein; MPO: myeloperoxidase; cTnI: cardiac troponin I
