To the Editor: Thompson's report highlighting the danger of baby walkers and the applicability of the proposed Australian mandatory standard is welcome.1 However, we have some concerns with the statement that the injury data used in the analysis are "largely representative of such events in the major proportion of metropolitan Australia". The only data sources used were the South Australian Department of Human Services Injury Surveillance System and the original Victorian Injury Surveillance System. Equivalent data from Queensland, although readily available, were not used.
