Measurements of IL-6, leptin and adiponectin in a subgroup of patients. Several relevant clinical parameters, such as BMI, waist–hip ratio and presence of MetS are shown. Median (IQR Q1–Q3) used in variables with non-normal distribution. Statistically significant p-values are bold.
BMI, body mass index; IL-6, interleukin 6 ; MDD, minimum detectable dose; MetS, metabolic syndrome; N, numbers.
