  1. Simple correlations and partial correlation adjusted for BMI among the PhA and anthropometric measurements, metabolic profile and bioelectrical variables. There was a significant negative association among the PhA and BMI, WC, lipid and hepatic profile, MetS and R and Xc; and significant positive association with HDL-cholesterol. In addition, after adjusting for BMI, the associations among the PhA, metabolic parameters and CRP levels remained still significant in psoriatic patients only
  2. Correlations among variables were analyzed using Pearson r or Spearman’s rho correlation coefficients. A p value in italic denotes a significant difference (p < 0.05)
  3. PhA phase angle, BMI body mass index, WC waist circumference, SBP systolic blood pressure, DBP diastolic blood pressure, HDL high-density lipoprotein, LDL low-density lipoprotein, AST aspartate aminotransferase, ALT alanine aminotransferase, MetS metabolic syndrome, CRP c-reactive protein, R resistance, Xc reactance
