Table 1.
Number of infants seen, mean (SD) birth weight (g), mean (SD) gestation (weeks), and median (25th, 75th centile) score on the clinical risk index for babies (CRIB) by hospital and number of infants seen in nine neonatal intensive care units. The clinical risk index for babies score ranges from 0 to 23; higher scores indicate an increased risk of hospital mortality. The total number of infants seen over the six years of the study was 2671
