Notes. CI: confidence interval; OR: odds ratio; BCAAs: branched-chain amino acids; MS: metabolic syndrome; L-Leu: L-leucine; L-Ile: L-isoleucine; and L-Val: L-valine. Definitions of BCAAs quartiles were in Statistical Analysis. Model 1: adjusting for age and gender; Model 2: adjusting for age, gender, current smoking status and drinking, and the administration of angiotensin converting enzyme inhibitors or angiotensin receptor blockers and MS components (systolic blood pressure, diastolic blood pressure, waist circumference, triglycerides and high density lipoprotein cholesterol, and fasting plasma glucose).
