Forest plot of all-cause death and CV death according to tertiles of TyG index in different HF phenotypes adjusted for model 2. HR hazard ratio, CI confidence interval, CV death cardiovascular death, TyG index triglyceride-glucose index, HF heart failure, HFrEF heart failure with reduced ejection fraction, HFmrEF heart failure with mildly reduced ejection fraction, HFpEF heart failure with preserved ejection fraction. ^aP for interaction between the TyG index and the HF phenotype with all-cause death as an endpoint, ^bP for interaction between the TyG index and the HF phenotype with CV death as an endpoint
