Fig. 4From: Subjective and objective survival prediction in mechanically ventilated critically ill patients: a prospective cohort studyCalibration of subjective survival estimates. In order to assess calibration, subjective survival estimates were plotted against observed survival. Subjective estimates deviate from perfect calibration, especially between 0 and 60% probability of survival (red line: perfect calibration; green line: 20% absolute overestimation of death)Back to article page
