Multiple stepwise regression analysis of independent factors associated with ZAG levels in all subjects.

Independent factors	Unstandardized coefficients (B) (95% CI)	Standardized coefficients (β)	value
Serum ZAG (R2 = 0.107)
Constant	7.804 (7.437–8.170)		0.037
Group (control, NCAD, CAD)	−0.474 (−0.625–0.324)	−0.328	<0.001
Urea	0.032 (0.001–0.064)	0.106	0.046

CI: confidence intervals. The following variables were also entered into multiple regression analysis but are not included in the equation: age; gender; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; FBG: fasting blood glucose; TC: total cholesterol; TG: triglycerides; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; ALT: alanine aminotransferase; Cr: creatinine.
