Restricted Cubic Splines (RCS) and Cox Proportional-Hazards Models for TyG Index and hsCAR with MACE. (A) Multivariable RCS regression shows the nonlinear association between the TyG index and MACE occurrence. The cut-off value of the TyG index for predicting MACE is 7.8. (B) Multivariable RCS regression shows the nonlinear association between hsCAR and MACE occurrence. The cut-off value of hsCAR for predicting MACE is 0.15. (C) Multivariable Cox regression analysis illustrates MACE occurrence in STEMI and hypertension patients by TyG index groups. (D) Multivariable Cox regression analysis illustrates MACE occurrence in STEMI and hypertension patients by hsCAR groups.
