      Ester Garne and Joan Morris are correct that the Born in Bradford birth cohort data for congenital anomalies do not include pregnancies that terminated before 28 weeks: the data we report refer to liveborn and stillborn infants only. We reported a protective effect of education on anomaly rates but we did not propose any theory to account for the finding because we had no further data that related to this observation.
