In the Original Investigation titled “External Validation of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) Risk Model to Predict Operative Risk in Perihilar Cholangiocarcinoma,”1 published online August 31, 2016, in JAMA Surgery, an error occurred in Figure 2. In the x-axis of the graph on the right, the label for the middle category of the fixed Comprehensive Risk Score, which read: “0.7 (n = 78)” should be replaced with “0.7 to <1.0 (n = 78).” This article was corrected online and in print.
