Table 3 HR (95% CI) for risk of myocardial infarction according to number of visits with a high TyG index

From: Triglyceride–glucose index is associated with the risk of myocardial infarction: an 11-year prospective study in the Kailuan cohort

Variables Number of visits with a high TyG index*
0 1 2 3 P for trend
Case, n (%) 173 (0.70) 139 (1.40) 126 (1.40) 164 (1.68)  
Incidence rate, per 1000 person-y 0.65 (0.56–0.75) 1.07 (0.91–1.27) 1.29 (1.09–1.54) 1.55 (1.33–1.81)  
Model 1 Reference 1.69 (1.36–2.12) 2.10 (1.67–2.64) 2.52 (2.03–3.12)  < 0.0001
Model 2 Reference 1.61 (1.28–2.01) 1.90 (1.50–2.40) 2.21 (1.77–2.76)  < 0.0001
Model 3 Reference 1.54 (1.23–1.93) 1.78 (1.41–2.26) 2.04 (1.63–2.56)  < 0.0001
Sensitivity analysis Reference 1.48 (1.16–1.91) 1.78 (1.37–2.31) 2.16 (1.69–2.78)  < 0.0001
  1. CI confidence interval, HR hazard ratio, TyG triglyceride glucose
  2. *High TyG index was defined as TyG index ≥ 8.83
  3. Model 1, adjusted for age and sex at baseline
  4. Model 2, adjusted for variables in model 1 plus level of education, income, smoking, alcohol abuse, physical activity, and BMI at baseline
  5. Model 3, adjusted for variables in model 2 plus SBP, DBP, a history of hypertension, diabetes mellitus, and dyslipidemia, antidiabetic drugs, lipid-lowering drugs, antihypertensive drugs, HDL-C, LDL-C, and hs-CRP at baseline
  6. Sensitivity analysis was adjusted for variables in model 3 and further excluded all deaths during the follow-up visits
