An editorial notes that as with most systematic reviews, this study seeks to answer a different question from that posed by the source studies, so caution is always required. It adds that though studies were carefully selected using prespecified inclusion and exclusion criteria, several potentially confounding factors could further complicate interpretation of the reported trends. Furthermore, social and financial factors can influence the likelihood that new people with diabetes are identified, and are driving action to achieve remissions through effective weight management programmes for people with type 2 diabetes. It suggests that if these programmes are provided for people with screen detected prediabetes, incidence of type 2 diabetes will fall. It concludes that overall that “this sensibly optimistic systematic review does not provide definitive evidence that true incidence is finally falling.”
