Errors in Text and Tables

JAMA. 2016;315(10):1057. doi:10.1001/jama.2016.0809

In the Original Investigation entitled “Effect of Lifestyle-Focused Text Messaging on Risk Factor Modification in Patients With Coronary Heart Disease: A Randomized Clinical Trial” published in the September 22, 2015, issue of JAMA,1 there were errors in the text and tables. In the table in the Abstract Results and in Table 2, the values in the physical activity row should have read “932 (825 to 1039), 587 (482 to 692), 345 (195 to 495), <.001” across the last 4 columns, respectively. In the text Results, in the first sentence of the “Effect of Objective Measures of Risk Factors” section, the word “change” should have read “difference” (“difference in LDL-C level, −5 mg/dL [95% CI, −9 to 0]; difference in systolic blood pressure, −7.6 mm Hg [95% CI, −9.8 to −5.4]; difference in BMI….”). The first sentence of the Discussion section should have read “Our study found that a simple, low-cost automated program of semipersonalized mobile phone text messages supporting lifestyle changes compared with usual care led to significant differences in LDL-C level….” In the Discussion section, the second sentence of the paragraph beginning “This study has a number of limitations…” should have read “First, the outcome was the difference in risk factor levels….” This article was corrected online.
