TNF and obesity due to melanocortin 4 receptor deficiency: Our study identified significant moderate-to-weak positive correlations between TNF-α levels and various obesity-related indices: WHtR (rho = 0.340, p-value = 0.046), WC (rho = 0.309, p-value = 0.027), WHR (rho = 0.279, p-value = 0.035), BAI (rho = 0.250, p-value = 0.018), and HC (rho = 0.194, p-value = 0.035).
