Error in Figure. In the Original Investigation by Nordmann et al titled “Effects of Low-Carbohydrate vs Low-Fat Diets on Weight Loss and Cardiovascular Risk Factors: A Meta-analysis of Randomized Controlled Trials,” published in the February 13 issue of the ARCHIVES (2006;166:285-293), an error occurred in Figure 6 on page 292. The graph labels “Favors Low Fat” and “Favors Low Carb” should have been reversed in both parts A and B of that figure. The corrected Figure 6 is reproduced here with its legend.
