“…Figure 3 shows the forest plot of AUC, O/E ratio, and O-E difference for isolated CABG, [7][8][9][10][11][12]17,21,24,26,27 isolated valve surgery, [8][9][10][11]19,24,27,29 and combined CABG and valve procedures. 10,11,18,24,27 Statistical heterogeneity was detected across studies for O/E ratio and O-E difference (P <.01 in each subgroup and overall). The euroSCORE II showed overall good discrimination in isolated CABG (AUC, 0.804; 95% CI, 0.771-0.837) and valve surgery (AUC, 0.777; 95% CI, 0.744-0.811).…”
