Probability of any clinically significant postoperative event requiring intensive care unit admission for the number of multivariate risk factors identified. Clinically significant postoperative event = cardiorespiratory and/or hematological event. The six multivariate risk factors include body weight <10 kg, American Society of Anesthesiologists class 3 or 4, packed erythrocyte transfusion >60 ml/kg, intraoperative complication, hemostatic blood product transfusion (platelets, fresh-frozen plasma, and/or cryoprecipitate), and tranexamic acid not given. Red line indicates predicted probability with dashed line indicating 95% CI around the predicted probability.
