In the Original Investigation entitled “Kidney Function After Off-Pump or On-Pump Coronary Artery Bypass Graft Surgery: A Randomized Clinical Trial” published in the June 4, 2014, issue of JAMA (2014;311:2191-2198. doi:10.1001/jama.2014.4952), the incorrect version of Table 1 was published. In Table 1, the title should have been “Baseline Characteristics of Patients in the CORONARY Kidney Function Substudy.” In the abbreviations list, after the abbreviation for CABG, “CORONARY, Coronary Artery Bypass Grafting Surgery Off- or On-pump Revascularisation Study;” should have appeared. In the footnote list, the “a” footnote should have started with “Values expressed as No. (%) unless otherwise indicated.” The “c” footnote should have been “The groups were not mutually exclusive (ie, a patient could have triple-diseased coronary vessels that included left main disease).” In the Table itself, the “Estimated GFR” row should have been “Estimated GFRd.” In the footnote list, the “d” footnote should have been “For patients with an estimated GFR greater than 60 mL/min/1.73 m2, the mean estimated GFR was 83 (SD, 12) mL/min/1.73 m2 with off-pump and 82 (SD, 13) mL/min/1.73 m2 with on-pump CABG surgery. For patients with an estimated GFR of 60 mL/min/1.73 m2 or less, the mean estimated GFR was 49 (SD, 9) mL/min/1.73 m2 with off-pump and 48 (SD, 9) mL/min/1.73 m2 with on-pump CABG surgery. The number of patients with an estimated GFR of 45 mL/min/1.73 m2 or less was 98 (6.7%) with off-pump and 110 (7.5%) with on-pump CABG surgery; and with an estimated GFR of 30 mL/min/1.73 m2 or less was 20 (1.4%) with off-pump and 15 (1.0%) with on-pump CABG surgery.” In the Table itself, the superscript “d” should not appear after the rows “>60 mL/min/1.73 m2” and “≤60 mL/min/1.73 m2.” The next row of the table should be “Urgent surgerye.” In the footnote list, the “f” footnote should have been “e” with the same text except for the last sentence, which should have been “Patients who required emergency CABG surgery (ie, immediate revascularization for hemodynamic instability) were not eligible for participation in the CORONARY trial.” This article was corrected online.
