  1. R-values are Spearman correlation coefficients. All correlations partialled for age, PAEE additionally partialled for weight. Partial r2 are from multiple linear regressions including age, and for PAEE, age and weight as covariates. PAEE, physical activity energy expenditure; ISIOGTT, Matsuda composite insulin sensitivity index; DIO, oral disposition index. Bold text indicates a statistically significant (p < 0.05) correlation.
