Threshold effect analysis of NHHR on all-cause and CVD mortality in participants with diabetes or prediabetes

	Adjusted HR (95%CI), P value
All-cause mortality
Total	1.03 (0.99, 1.08) 0.104
Segmented cox proportional hazards model
Inflection point	2.72
NHHR < 2.72	0.76 (0.68, 0.85) 0.001
NHHR ≥ 2.72	1.11 (1.06, 1.16) 0.001
P for Log-likelihood ratio	< 0.001
CVD mortality
Total	0.98 (0.90, 1.06) 0.568
Segmented cox proportional hazards model
Inflection point	2.83
NHHR < 2.83	0.70 (0.57, 0.85) 0.001
NHHR ≥ 2.83	1.08 (1.00, 1.16) 0.027
P for Log-likelihood ratio	0.001

The model was adjusted for sex, age, race, education, marital status, poverty income ratio, BMI, smoking status, drinking status, physical activity, hypertension, hyperlipidemia, antihyperglycemic treatment, lipid-lowering treatment, and antihypertensive treatment
