  1. Spearman correlation coefficients have been adjusted for age, sex, and baseline BMI.
  2. CISI, composite insulin sensitivity index; HOMA, homeostasis model assessment.
  3. a Values were log transformed due to significant departures from normality.
  4. b One participant missing baseline fasting glucose measurement (Decaffeinated coffee treatment group).
  5. c P-value < 0.05.
