Relationship between rheumatoid factor (RF) and anti-nuclear antibodies (ANA) with Gensini score (log transformed) in study population

Study groups	Crude				Adjusted model
	RF		ANA		RF		ANA
	Standard beta	P	Standard beta	P	Standard beta	P	Standard beta	P
ACS	-0.073	0.55	0.400	0.001	-0.102	0.880	0.505	< 0.001
CSA	-0.020	0.87	0.037	0.767	-0.034	0.797	0.013	0.922

Adjusted model: For controlling the effect of age and other confounder factors such hypertension, diabetes, hyperlipidemia and smoking we used multiple linear regression; RF: Rheumatoid factor; ANA: Anti-nuclear antibodies; ACS: Acute coronary syndrome; CSA: Chronic stable angina
