Comparison of LR1 model and LR2 for predicting in-hospital all-cause mortality. A NRI was calculated in the training cohort. we used 10% and 30% as thresholds to define low-risk (< 10%), intermediate-risk (10–30%), and high-risk (> 30%) patients. the IDI is also listed above. B Calculation of NRI and IDI in the test cohort
