Fig 1 Assessment of surgical mortality risk by subjective assessment (top panel) and, statistical model (bottom panel). (CI = confidence interval.) The Annals of Thoracic Surgery 1999 67, 635-640DOI: (10.1016/S0003-4975(98)01326-5)

Fig 2 Calibration curve of predicted versus observed mortality rates by risk level of surgeons’ subjective assessment. The Annals of Thoracic Surgery 1999 67, 635-640DOI: (10.1016/S0003-4975(98)01326-5)

Fig 3 Relation between subjective surgical risk level and individual patient score according to the statistical model. (Box indicates the lower and upper quartiles and the central line the median. Points at the ends of the “whiskers” are the 2.5% and 97.5% values of the cumulative relative frequencies.) The Annals of Thoracic Surgery 1999 67, 635-640DOI: (10.1016/S0003-4975(98)01326-5)
