Numeric Errors in Results, Table, and Figures 2-4

In the Original Investigation, “Association Between Use of Enhanced Recovery After Surgery Protocol and Postoperative Complications in Colorectal Surgery: The Postoperative Outcomes Within Enhanced Recovery After Surgery Protocol (POWER) Study,”¹ published online on May 8, 2019, and in the August 2019 issue of JAMA Surgery, there were numeric errors. In the Results section, the percentage of patients with moderate to severe complications was 7.06% vs 7.56% (and not 25.2% vs 30.3%), and the P value for reduction in rates of urinary tract infection was .03 (not .04) and for infection of uncertain origin was .04 (not .02). In addition, this text was removed because of inaccurate interpretation: “and had a significant increase in patients in whom no antibiotic prophylaxis was performed (OR, 0.38; 95% CI, 0.14-1.03; P = .09).” In the Table, errors in numbers in the first to second decimal places for some values and typographical errors have been corrected. In Figure 2, total was run from the arrhythmia complication, so that all subsequent totals were incorrect. In Figures 2 and 3, the numbers of moderate or severe complications were incorrectly reported. In Figures 3 and 4, there were a few errors in the numbers in the first or second decimal place. The authors have confirmed that these errors do not affect the interpretations of conclusions of this study. These errors have been corrected in the article.
