  1. Bold indicates P < 0.05
  2. The multivariable model showed a good calibration as assessed by the Hosmer and Lemeshow goodness of fit test [p = 0.98] and a fair discrimination as assessed by the receiver operating characteristics curve [area under the curve (AUC) 0.89; 95% CI 0.80–0.97; p < 0.001] (Fig. 4)
  3. CI confidence interval, CV cardiovascular, LAScd left atrial strain during conduit phase, SOFA sequential organ failure assessment, PEEP positive end-expiratory pressure. NR not retained in the final model, NS not significant in the final model
