Correlations between IgM antibody levels and complement factors.

IgM anti-	C3		C4
	r	p	r	p
PC	0.031	0.7364	0.065	0.4851
MDA	–0.24	0.0086^*	–0.14	0.13
β2-GPI	–0.22	0.015^*	–0.31	0.0007^*
CL	–0.27	0.0078^*	–0.41	<0.0001^*
dsDNA	–0.19	0.068	–0.23	0.025^*

r-Values and p-values are presented from Spearman (rank-based) analysis on logarithmic transformed data.

Some samples were insufficient for all tests. Some patients did not have laboratory values for C3 and C4 available. IgM anti-CL, anti-dsDNA: n=93; all other: n = 118.

Statistical significant correlation.
