*Beta-coefficients represent the mean difference between dietary groups (LCHF vs UC) in the A1C change (A1C at that follow-up visit−A1C at baseline).
†Model 1 is unadjusted; model 2 is fully adjusted for baseline characteristics at visit 1, including sex, A1C, BMI and dose of insulin in units.
LCHF, low carbohydrate, high fat; UC, usual care.
