Incorrect evidence evaluation and study statistics. The FPIN's Help Desk Answers, “Wearable Devices for Weight Loss” (December 1, 2018, p. 670), contained two errors. The first was in the first sentence of the “Evidence-Based Answer” section (page 670), which should have read, “There is conflicting evidence about the effectiveness of adding a wearable device to intensive lifestyle interventions for weight loss.” The second error involved the statistics listed in the next to last sentence of the first paragraph of the “Evidence Summary” section, which should have read, “Patients in the intervention group did not lose weight over the 24-month period in comparison to the control group (7.7 lb [3.5 kg] vs. 13 lb [5.9 kg], respectively; mean difference = 5.3 lb [2.4 kg]; 95% CI, 2.2 to 8.2 lb [1.0 to 3.7 kg]).” The online version of the article has been corrected.
