Baseline characteristics of the clinical data set. Data presented as cases/number (percentage), mean (SD), or median (IQR), as indicated. CKD indicates chronic kidney disease; eGFR, estimated glomerular filtration rate; hs‐cTnT, high‐sensitivity cardiac troponin T; IQR, interquartile range; NSTE‐AMI, non–ST‐segment elevation acute myocardial infarction.
