Neonatology Fellowship, Division of Neonatology, and b Department of Child Health, University of Missouri Health Care System, Columbia, Mo., USA when an association is evaluated,(b) even if a strong association is observed, other evidence is required to support causation, and (c) no matter how precisely a study is conducted, bias cannot be totally eliminated. Considering the aforementioned admonitions, the nine viewpoints articulated by Hill can be used as a framework to evaluate the research performed by Ismail et al.[1]. We ascertain whether their hypothesis is more or less plausible.Based on information provided in the paper by Ismail et al.[1], it is difficult to determine the strength of association between a change in milk processing and emergence of neonatal GBS disease. This is particularly true when other concurrent events are considered in causation. Although the timeline is rather short in the number of years, the change in milk transport does come before the increase in neonatal GBS infections in the UK. Thus, a most important criterion among Hill’s viewpoints, namely temporality, is fulfilled. The association between neonatal GBS disease and a change in milk processing should have consistency among different populations. In the USA, bulk transport of milk from dairy farms to the processing plant began before 1920 and was widely established by 1940 [7]. Thus, bulk transport of milk to the processing plant occurred at least two decades before the emergence of the neonatal GBS epidemic in the USA. This observation suggests alternative associations may be
