  1. aIntention-to-treat with multiple imputation repeated-measures mixed-model analysis with age and race as covariates. n = 112 for LG and n = 83 for SG for all analyses except those for BP, total cholesterol and HbA1c. Adjustments were made to the sample to exclude for BP, lipid lowering, and diabetes medication use. For BP: n = 71 for LG and n = 47 for SG. For total cholesterol: n = 97 for LG and n = 65 for SG. For HbA1c: n = 101 for LG and n = 80 for SG. Statistically significant P values are shown in bold
  2. bAll values are model predicted means; 95% CIs in parentheses
  3. cAnalyses conducted using log-transformed values
