Variables are expressed as mean (± SD); p: P-value for the comparisons (means) between levels of the different categories; ¹: P-value for the Model 1 (unadjusted); ²: P-value for Model 2 (adjusted for sex, age and obesity); ³: P-value for Model 3 (Model 2 additionally adjusted for diabetes and medications). A total of 484 subjects were analyzed for the comparisons.
