The associations of the triglyceride-glucose index and its combination with blood pressure on cardiovascular and all-cause mortality in hypertension: a national study

Figures

  Figure 1. Restricted cubic spline models for the association between triglyceride-glucose index and mortality. Adjusted hazards ratio (solid pink lines) and 95% confidence intervals (pink shadow) after controlling covariates in Table 1 for (A) cardiovascular mortality, (B) all-cause mortality. Splines were examined in the fully adjusted model with the best placed knots at the 10th, 50th, and 90th percentiles of triglyceride-glucose index.

  Figure 2. The Kaplan–Meier curves after controlling covariates in Table 1 for cumulative hazards of the mortality in individual TyG index analysis. (A) Cardiovascular mortality, (B) all-cause mortality. TyG index, triglyceride-glucose index. Lower TyG index was defined by TyG index <9.5551 and <9.3405 in cardiovascular and all-cause mortality, respectively. Higher TyG index was defined by TyG index ≥9.5551 and ≥9.3405 in cardiovascular and all-cause mortality, respectively.

  Figure 3. The Kaplan–Meier curves after controlling covariates in Table 1 for cumulative hazards of the mortality in joint groups. (A) Cardiovascular mortality, (B) all-cause mortality. RIRR, residual insulin resistance risk, SBP <140 mmHg and DBP <90 mmHg, and with TyG index ≥ estimated threshold; RBR, residual blood pressure risk, SBP ≥140 mmHg or DBP ≥90 mmHg, and with TyG index < estimated threshold; RBIRR, residual blood pressure and insulin resistance risk, SBP ≥140 mmHg or DBP ≥90 mmHg, and with TyG index ≥ estimated threshold.
