From an international perspective, the
incidence of breastfeeding is extraordinarily high
in both groups: 87% of the PT infants and 74%
of the VPT infants were breastfed at 1 month of
corrected age; at 6 months of corrected age, the
corresponding figures were 58% and 43%. In addition,
nearly 9 of 10 infants were fed breast milk at
breast and not by other methods, data that seem to
be disregarded in many studies
