"Hypovitaminosis D and Metabolic Inflammatory Status in Patients With Obesity"

Blood test measured in ng/ml

Measurements of body composition were conducted with Bioelectrical Impedance Analysis (BIA) technique, asking the participants to stand on the device barefoot to complete the analysis. Among all parameters, BMI, phase angle (PhA), total body water (TBW), extracellular (ECW) and intracellular water (ICW), body fat index, and fat and muscular mass were recorded.

Ferritin plasma levels were measured in μg/L

CRP plasma levels were measured in mg/L

Glasgow Prognostic Score/modified Glasgow Prognostic Score (GPS/mGPS), Prognostic Nutritional Index (PNI), Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte ratio (PLR), Lymphocyte-to-monocyte ratio (LMR), Systemic immune-inflammation index (SII) were calculated using blood test results

A liver biopsy was used to study nonalcoholic steatohepatitis (NASH) and fibrosis according to the Kleiner-Brunt classification
