Errors in Abstract, Table, and Discussion

In the Original Investigation titled “Effect of Bimagrumab vs Placebo on Body Fat Mass Among Adults With Type 2 Diabetes and Obesity: A Phase 2 Randomized Clinical Trial,”¹ published January 13, 2021, there were errors in the Abstract, Table, and Discussion. In the Abstract, the change in hemoglobin A_1c in the placebo group should have been 0.04 percentage points. In Table 2, the P value for the Matsuda index should have been .10. The first paragraph of the Discussion should have referred to a 0.5% decrease in body fat mass and a 0.04–percentage increase in hemoglobin A_1c in the group that received placebo and lifestyle intervention. This article has been corrected.¹
