Table 3 Comparison of the SLEDAI score between positive and negative patients for anti-dsDNA, anti-nucleosome, and anti-smith

From: Co-positivity of anti-dsDNA, anti-nucleosome, and anti-smith autoantibodies as serological biomarkers for disease activity in systemic lupus erythematosus

Antibodies	Frequencies	n (%)	SLEDAI	P value
Anti-dsDNA	Positive	70 (87.5%)	18.63	< .001***
Anti-dsDNA	Negative	10 (12.5%)	6.5
Anti-nucleosome	Positive	62 (77.5%)	19.79	< .001***
Anti-nucleosome	Negative	18 (22.5%)	7.88
Anti-smith	Positive	34 (42.5%)	21.94	0.002**
Anti-smith	Negative	46 (57.5%)	13.54

The difference between SLEDAI in positive and negative groups of autoantibodies is a very high significant difference at p < 0.001
**the significance is high; ***the significance is very high
