Partial correlation heat matrix at 0, 6, and 18 weeks between different bile acids (BA) and insulin resistance (IR) measures, intrahepatic lipid content (IHL) and fibroblast growth factor-19 (FGF-19) plasma levels, when corrected for age and body mass index (BMI), in the pooled cohort (n = 72; all four dietary groups and overweight and obese participants combined)

Bold font denotes significant correlations at α = 0.05; strength of color indicates the magnitude of the Pearson’s correlation value (r); red indicates positive and blue indicates negative correlations
