Cl was positively correlated with number of MetS criteria (p = 0.042), BW (p = 0.020), BMI (p < 0.001), HC (p < 0.001), %fat (p < 0.001), fat mass (p < 0.001), insulin (p = 0.003), HOMA-IR (p = 0.004), eGFR (p < 0.001), serum leptin (p < 0.001), and HF nu (p = 0.045), while it was negatively correlated with WHR (p = 0.045), QUICKI (p = 0.018), BUN (p = 0.007), Cr. This evidence concerns the gene LEP and metabolic syndrome.
