Units of Measure Error

In the Original Investigation entitled “Effect of Low-Fat vs Low-Carbohydrate Diet on 12-Month Weight Loss in Overweight Adults and the Association With Genotype Pattern or Insulin Secretion: The DIETFITS Randomized Clinical Trial”¹ published in the February 20, 2018, issue of JAMA, there were units of measure errors for 3 variables in Table 3. In Table 3, “lipid level” row, the units of measure should be “mg/dL” and the “SI conversion factors” footnote should read “To convert high-density and low-density lipoprotein cholesterol to mmol/L, multiply by 0.0259; triglycerides to mmol/L, multiply by 0.0113.” This article was corrected online.
