Adjusted for allocation status in nesting trial

Adjusted for allocation status, for maternal age, education, parity, pre-pregnancy body mass index, smoking status, and social class, and for child sex, age at dental assessment, length-forage Z-score (6 months), exclusive breastfeeding duration, and use of nursing bottle (6 months)
