In the Original Investigation entitled “Systemic Review and Meta-analysis of Randomized Clinical Trials Comparing Primary vs Delayed Primary Skin Closure in Contaminated and Dirty Abdominal Incisions” published in the August 2013 issue of JAMA Surgery (2013;148[8]:779-786. doi:10.1001/jamasurg.2013.2336), incorrect information appeared. In the first sentence of the Primary Outcome subsection of the Results section, the P value for chance of surgical site infection should be .02. In Table 1, Table 2, and Figure 2, the source “Chang et al22” should be “Chiang et al15.” This article was corrected online.
