BMI, body mass index; CDI, concentrated disadvantage index; CRP, C-reactive protein; DBP, diastolic blood pressure; HbA1c, hemoglobin A1c; MBG, mean blood glucose; SBP, systolic blood pressure; SEM, standard error of the mean.

^*Values are means ± SEM.

^†Differences between groups were determined by chi-squared or Wilcoxin–Mann–Whitney tests.

^‡MBG was calculated from an average of 111 ± 9 glucose meter observations during the 30-day collection period.
