Multivariate analysis for risk factors of anti-IL10 antibody with SLE

Parameters	Univariate			Multivariate
	OR	95% CI	P-value	OR	95% CI	P-value
Age (years)	0.951	0.906–0.998	0.031	0.925	0.864–0.990	0.0118
IgG (mg/dL)	1.002	1.000–1.003	<0.001	1.002	1.001–1.003	0.0003
Low C3	0.131	0.027–0.643	0.004	0.268	0.041–1.741	0.1449

Notes: Data were analyzed with univariate/multivariable analysis. High level of serum IgG is associated with anti-IL-10 antibody positive.

Abbreviations: IgG, immunoglobulin G; Low C3, C3 >65 mg/dL (less than reference value); SLE, systemic lupus erythematosus.
