Fig. 5From: Machine learning approach for predicting post-intubation hemodynamic instability (PIHI) index values: towards enhanced perioperative anesthesia quality and safetyThe average ratings of anesthetists and the computed ICA values. The ICA values are consistent with the human ratings, with Spearman correlation coefficient of 0.877 (P < 0.001).
