Beta coefficients show differences in F2-isoprostanes index associated with a change in acylcarnitines (log-transformed) equal to standard deviation. Minimally adjusted models included the demographic variables (age, gender, and race/ethnicity) and BMI; fully adjusted models included additional metabolic variables (IGT-status, insulin sensitivity, and AIR). Statistically significant results ( < 0.05) are in bold.
