Figure. Comparison of mean weight loss in kg between participants on the conventional diet and participants on the low-carbohydrate diet at 6 months (n= 118) and at 1 year (n= 126). *P = 0.003 for comparisons between diet groups by random-coefficient analysis. The difference in weight loss was not significant between the 2 diet groups by 1 year (P = 0.195 before and P > 0.2 after adjustment for baseline variables, by random-coefficient analysis). Error bars represent SDs.
