N2  - In Reply.—Dr Hack's first point, regarding providing hospitalization data on all very-low-birth-weight infants, including those not seen on follow-up, does not pertain to the interpretation of our study results. As stated in the report, the purpose of our study was to assess growth differences at followup between two cohorts of infants with similar size and degree of illness who were treated 4 years apart. As described in Table 1 of the report, the cohorts were carefully matched for gestational age, weight, and degree of illness at presentation. Presentation of data on infants not subsequently seen on follow-up would serve no useful purpose in elucidating the neonatal factors that influenced follow-up growth rates of those seen.The second point, regarding the low follow-up rate at 1 year, was a difficult one during analysis of the study results. We carefully stated in the report that there might be selection bias in those children
