Triglyceride-glucose index and all-cause mortality in patients with chronic severe heart failure

Table 5 Exploratory subgroup analyses for the association between triglyceride-glucose index and 5-year all-cause mortality

Subgroup	n	Events	Adjusted HR	95%CI	P value	P for interaction
Diabetes mellitus	119	77	1.28	0.91-1.80	0.156	0.684
No diabetes mellitus	142	58	1.31	0.89-1.94	0.172
Age < 65 years	110	39	1.24	0.78-1.97	0.361	0.522
Age ≥ 65 years	151	96	1.39	1.01-1.92	0.044
Male	165	84	1.36	0.98-1.89	0.067	0.744
Female	96	51	1.29	0.82-2.04	0.269
eGFR < 60 mL/minute/1.73 m2	137	86	1.42	1.01-2.01	0.046	0.438
eGFR ≥ 60 mL/minute/1.73 m2	124	49	1.21	0.79-1.86	0.382

Subgroup analyses were exploratory and were not adjusted for multiple comparisons. Adjusted hazard ratio refer to each 1-unit increase in triglyceride-glucose index. HR: Hazard ratio; CI: Confidence interval; eGFR: Estimated glomerular filtration rate.
