BW, birth weight; GA, gestational age; sRPL, secondary recurrent pregnancy loss; p-MBL, plasma mannose-binding lectin; OR, odds ratio.

^aData on one set of twins and eight stillbirths were not included in the analysis of gestational age and birth weight.

^bExcluded from analysis: 15 women with children of both sexes of previous births.

^cOR 2.36 95% CI: 1.02–5.49 comparing p-MBL level ≤500 µg/l to p-MBL levels >500 µg/l.
