    Editor—In our study1 we referred to research conducted by the Scottish Low Birthweight Study Group on developmental outcomes among a birth cohort of Scottish very low birthweight (VLBW) infants born in 1984. We stated that the Scottish study had yet to publish data on school aged outcomes among this cohort, and further that the study lacked comparative data on outcomes among a general child population sample.

    It has been pointed out to us that both of these claims are, in fact, incorrect. The Scottish Group has published findings on the school attainment, cognitive ability, and motor function of their cohort at age 8 years,2 and included, as part of their analyses, comparative outcome data for a general child sample matched for age and gender with the VLBW cohort and selected from the same school classes in which the VLBW cohort members were enrolled. Our own findings, based on a New Zealand birth cohort, show strong parallels with the Scottish study, particularly in relation to the higher rates of educational problems and poorer cognitive functioning experienced by VLBW children in comparison to their peers. It would have been useful to draw these comparisons in the discussion of our own findings. We very much regret this oversight on our part and apologise to the Scottish Group for our error.
