Values are No. (%) or as otherwise indicated. ESC/ERS = European Society of Cardiology and the European Respiratory Society; TDCI = thermodilution cardiac index. See Table 1 legend for expansion of other abbreviations.
a
Risk category that are concordant between the cardiac index and the comparator risk variable.
