  1. 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
  2. BMI Body Mass Index, SBP systolic blood pressure, DBP diastolic blood pressure, WC Waist Circumference, CRP C-reactive protein, HDL High-density lipoprotein, LDL low-density lipoprotein, AST aspartate aminotransferase, ALT Alanine transaminase, γGT γ-glutamyltransferase, HoMA-IR Homeostatic Model Assessment for Insulin Resistance, VAI Visceral Adiposity Index, FLI Fatty Liver Index, HS Hepatic Steatosis, MetS Metabolic Syndrome
