Results	SLE patients (n = 58) Median plasma conc. μg/ml (range)	Healthy controls (n = 65) Median plasma conc. μg/ml (range)	Mann–Whitney P-value
CL-L1	0·25 (0·16–0·37)	0·31 (0·20–0·51)	<0·001
CL-K1	0·33 (0·22–0·45)	0·34 (0·25–0·50)	0·033
MBL	0·75 (0·00–3,25)	0·70 (4–4,203)	0·520
M-ficolin	0·30 (0·01–1·01)	0·49 (0·16–1·63)	<0·001
