IL6 and obesity due to melanocortin 4 receptor deficiency: After adjustment for age and sex, high IL-6 mRNA expression was also associated with obesity (AOR = 3.11, 95% CI = 1.74–5.56, p = 0.0001) and NAFLD (AOR = 2.59, 95% CI = 1.03–6.52, p = 0.042) and inversely associated with HBV (AOR = 0.34, 95% CI = 0.17–0.65, p = 0.0013).
