HbA1c = glycated hemoglobin; SBP = systolic blood pressure.
Note: Outcomes were analyzed using a linear mixed model including all possible interactions between diet, support, and time and adjusted for age and sex. Results are presented collapsed over all other factors: diet, sex, and at the mean value of age. The between-group P value is calculated from a Z test based on the estimated mean changes and the associated SE values reported in the table.
