MBL level according to (extended) MBL2 haplotypes in patients with juvenile polyarthritis and oligoarthritis. Median mannose-binding lectin (MBL) plasma levels, represented by horizontal lines, differ between extended haplotype groups (P < 0.01), but not between patients with oligoarthritis (n = 151) and polyarthritis (n = 67) who had similar haplotypes (P > 0.46).
