Spearman correlation coefficients have been adjusted for age, sex, and baseline BMI.

CISI, composite insulin sensitivity index; HOMA, homeostasis model assessment.

a Values were log transformed due to significant departures from normality.

b One participant missing baseline fasting glucose measurement (Decaffeinated coffee treatment group).

c P-value < 0.05.
