  1. Note: Adjusted for age group, gender, occupation, education, monthly income, current smoking, current drinking, physical activity, ASCVD, liver, kidney, and thyroid dysfunction
  2. Considering ordinal BMI, interactions of abnormal status of non-traditional CVRF and BMI were more interested. Additive interaction RERI(95%CI): HUA + abnormal BMI: 2.521(0.793–4.250); HHCY + abnormal BMI: 0.589(-0.182-1.360); HHsCRP + abnormal BMI: 1.255(0.028–2.483). Multiplicative interaction OR(95%CI): HUA * abnormal BMI: 1.408(0.881–2.250); HHCY * abnormal BMI: 1.002(0.734–1.368); HHsCRP * abnormal BMI: 1.187(0.767–1.837)

Abbreviations: CVRF, cardiovascular risk factors; MetS, metabolic syndrome; BMI, body mass index; UA, uric acid; HUA, hyperuricemia; HCY, homocysteine; HHCY, hyperhomocysteinemia; HHsCRP, high hypersensitive C-reactive protein; ASCVD, arteriosclerotic cardiovascular disease; RERI, relative excess risk due to interaction; OR, odds ratio; CI, confidence interval
