Table 3 Correlations among body composition evaluated by BIA, PASI score and CRP levels in psoriatic patients

From: Nutrition and psoriasis: is there any association between the severity of the disease and adherence to the Mediterranean diet?

  1. Correlation among BIA parameters, PASI score and CRP levels were performed using Pearson r correlation coefficient. BIA, Bioelectrical impedance analysis; PASI, Psoriasis Area Severity Index; CRP, C-reactive protein; R, Resistance (Ω = ohm); Xc, Reactance (Ω = ohm); PA, Phase Angle (° = degrees); R/H, Resistance standardized by Height (Ω/m = ohm/meters); Xc/H, Reactance standardized by Height (Ω/m = ohm/meters); Na/K, Sodium/Potassium; BCMI, Body Cell Mass Index; FM, Fat Mass; FFM, Fat-Free Mass; BCM, Body Cell Mass; SMM Skeletal Muscle Mass; TBW, Total Body Water; ECW, Extra-Cellular Water; ICW,Intra-Cellular Water.
