Resistin, a cytokine involved in insulin resistance, showed positive correlations with BMI (r=0.512, p=0.009) and visceral adiposity index (r=0.557, p=0.008), consistent with previous studies by Jiang et al. and Su et al. linking resistin to obesity-related insulin resistance [18,19]. Here, RETN is linked to obesity due to melanocortin 4 receptor deficiency.
