Values are log transformed regression coefficients (95% confidence interval of cell numbers (*10e9/L)) derived from linear regression models and reflect the increase or decrease (%) in log transformed cell numbers of partial and exclusive breastfed groups relative to the reference group (never breastfeeding). Partial breastfeeding indicates infants receiving both breast-feeding, bottle feeding and/or solids in this period.
*P-value <0.05. Adjusted for maternal education and maternal alcohol use during pregnancy.
