Clarification of the Number of References and Studies Used in Review

JAMA. 2015;314(14):1521. doi:10.1001/jama.2015.12071

In the Review entitled “Nonalcoholic Fatty Liver Disease: A Systematic Review” published in the June 9, 2015, issue of JAMA,1 the number of references was correct; however, the numbers for the individual study categories were incorrect. In the “Evidence Review” section of the abstract, the last sentence should be “A total of 88 references were selected, including 14 randomized clinical trials, 19 cohort or case-control studies, 1 population-based study, 2 practice guidelines, 7 meta-analyses, 43 classified as other, and 2 webpages.” In the “Literature Search” section, first full paragraph, the last sentence should be “For NAFLD and cirrhosis, there were 3396 identified, 163 clinical studies reviewed, and 31 referenced; mortality, 537 identified, 163 clinical studies reviewed, and 11 referenced; biomarkers, 1117 identified, 73 clinical studies reviewed, and 31 referenced; and treatment, 3107 identified, 223 clinical studies reviewed, and 33 referenced.” The following new sentence will become the last sentence of this paragraph: “The same study often appeared in more than 1 search.” In the next paragraph of this section, the last sentence should be “Overall, 14 randomized clinical trials, 19 cohort or case-control studies, 1 population-based study, 7 meta-analyses, 2 practice guidelines, and 43 classified as other were used for this analysis (additional details appear in the eFigure in the Supplement).” In addition, in Figure 1, the word “is” has been added 3 times to the legend to improve readability. In Figure 3, the abbreviation “AFRI” has been changed to “ARFI” in the figure itself and in the legend. In the eFigure, the numbers of studies for 2 boxes in the last row of the figure were changed and the following sentence was added as a figure legend: “The same study often appeared in more than 1 search.” This article was corrected online.
