This difference in distribution was dismissed as not significant (χ2, 2.51; P=.11). However, black, very low-birth-weight infants have lower mortality rates than white newborns of comparable weights nationally, and when compared internationally, the black, very small newborn also has lower mortality rates than those of other industrialized countries.2 Als et al have aggregated their black and white patients, ignoring longstanding epidemiological evidence that "quality of medical care cannot be evaluated in a meaningful way using aggregated data."3Not surprisingly, lower mortality rates are associated with lower morbidity. Black premature infants have significantly less hyaline membrane disease than white premature infants. In addition, the disease is less
