  1. AP, proportion attributable to interaction; CI, confidence interval; RERI, relative excess risk due to interaction; SI, synergy index
  2. a Model 1 was adjusted for age, gender
  3. b Model 2 was adjusted for age, gender, marital status, residence, education level, smoking status, and drinking status
  4. c Model 3 was adjusted as model 2 plus hypertension, diabetes, heart disease, dyslipidaemia, kidney disease, and history of medication use for hypertension, diabetes, and dyslipidaemia
