Exploratory analyses performed on outcome variables with significant effects from Paleolithic diet compared to Diabetes diet. Analyses consisted of bivariate correlations between within-subject differences (Δ) in outcome and dietary variables. Significantly correlating variables were entered into a stepwise forward linear regression analyses. *P for bivariate correlation between variables in a two-sided t-test. §P for stepwise forward linear regression analyses entering significantly correlated variables. NS = Not Significant. NE = Weight and BMI not entered in their respective regression analysis due to calculatory relatedness.
