Results
During the period of the study, 241 preterm infants with
birth weights below 1,500 g and gestational age below 33
complete weeks were admitted to the neonatal ward. Of these,
full and informed consent was given for 98 to participate in
the randomization process. However, only 96 preterm infants
remained in the study until the 6th month of corrected age
(47 for the experimental group and 49 for the control group)10
