| Fasting glucose (mg/dL) | 110.0 (53.3) | 112.3 (53.7) | 2.4 (13.5) | +2.1% | 0.28 |
Abbreviations: BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; HDL, high-density lipoprotein; LDL, HDL, low-density lipoprotein.
a
N = 39 instead of 40 because measurements were not available for one participant due to a logistical lab error.
b
The baseline to postintervention difference for continuous variables were tested using 1-sample paired Student’s t tests. P < .05 indicates statistically significant differences.
c
LDL measures were only taken in Cohort 2, N = 20.
