Data are shown stratified according to the extent of myocardial injury defined by high sensitivity cardiac troponin I values (99th percentile cut-off).
Data are presented as percentage, mean, or median as appropriate. eGFR denotes estimated glomerular filtration rate, hs-cTnI denotes high sensitivity cardiac troponin I.
