Basic characteristics of the transfused and non-transfused infants
| Non-transfused infants (n=22) | Transfused infants (n=12) | p Value | |
|---|---|---|---|
| Values are median (interquartile range) unless otherwise indicated. The number of infants transfused was 12, but some were studied on more than one occasion so the number of transfusions was 20. The percentages are calculated on the basis of the number of transfusion episodes. | |||
