Mean ratio (95% CI) of AF-alb in October compared with February with respect to change in weaning status over the study period.

		GM AF-alb (pg/mg)		Ratioa of AF-alb in October compared to February (95% CI)
Weaning groupb	No.c	February	October	Unadjusted	Adjustedd
Weaned at entry	123	54.4	99.4	1.8 (1.5–2.2)	1.6 (1.2–2.1)

^aThe ratio of the AF-alb level in February and that in October was calculated for each child, and then the GM of these ratios was calculated for each group.

^bChildren who were fully weaned at the start of the study are categorized as “weaned at entry.” Those who remained partially breast-fed throughout the study period, “not weaned”; those who were partially breast-fed in February but were fully weaned by June or October.

^cNineteen of the 200 children had incomplete information on weaning status or missing data on AF-alb.

^dANOVA test, p = 0.0046 after adjusted for age at recruitment, village, and SES.

^*p = 0.068 compared with weaned at entry group;

^**p < 0.0001 compared with weaned at entry group.
