The dose-response relationship between serum chloride and the risk of MetS and its components. Serum chloride was observed to non-linear negative correlated with MetS (a), raised FG (b), and TG (c), non-linear positive linked with reduced HDL-C (d), and linear inversely related with raised BP (f), but has no significantly association with raised WC (e). Abbreviation: MetS, metabolic syndrome; FG, fasting glucose; TG, triglycerides; BP, blood pressure; WC, waist circumference; HDL-C, high density lipoprotein cholesterol
