↵Baseline data are means ± SD. Some data are missing or not recorded in the chart to account for less than the total numbers in each group.
*Sixteen missing values were recorded as ‘high’ by the glucometer (ie, >600 mg/dL) and were recorded as unmeasurable in the chart.
BHB, beta-hydroxybutyrate; BMI, body mass index; BUN, blood urea nitrogen; HgbA1c, hemoglobin A1c.
