At simple correlation, PASI score was significantly association with BMI, WC, CRP levels, metabolic profile, liver function tests, and the cardio-metabolic indices. After adjusting for BMI the associations between PASI score and the study variables were mainly preserved. Correlations between variables were performed using Pearson r and Spearman’s rho correlation coefficients. Italicized p-values represent significant differences at p < 0.05
