1
HOMA-IR, homeostasis model assessment of insulin resistance.
2
P for treatment by follow-up interaction as determined by using a general linear model for correlated data with PROC MIXED, an unstructured covariance matrix, and standard restricted maximum likelihood estimation in SAS (SAS Institute Inc, Cary, NC).
3
Mean ± SD (all such values).
4
Median; first and third quartile cutoffs in parentheses (all such values).
