L-shaped association between the GA/HbA1c ratio and all-cause mortality in U.S. adults with NAFLD: a cross-sectional study from the NHANES 1999–2004

Table 2 Threshold effect analysis of GA/HbA1c ratio on all-cause mortality in NAFLD patients

	Adjusted HR (95% CI), P-value
All-cause mortality
Fitting by the standard linear model	1.22 (1.05, 1.42), 0.009
Fitting by the two-piecewise linear model
Inflection point	2.21
GA/HbA1c ratio < 2.21	0.52 (0.26, 1.02), 0.054
GA/HbA1c ratio ≥ 2.21	1.33 (1.14, 1.60), <0.001
P for Log-likelihood ratio	0.015

Analysis was adjusted for age, sex, race, education level, marital status, poverty income ratio, hypertension, diabetes, cardiovascular disease, cancer, smoker, physical activity, estimated glomerular filtration rate, body mass index and nafld fibrosis score
