I continue to be impressed with the output of published reports stemming from the data of the Endophthalmitis Vitrectomy Study (EVS) Group. However, I have concerns regarding some of the conclusions presented by Dr Doft and coworkers in their most recent publication.1 The authors should accept the implications of the statistical analysis of their results instead of making statements that are not supported by their data. After reading their article, my interpretation is that when the data support the notion that diabetics should have more problems, it is reported, even when there is no "significant difference" to support this assumption. When the diabetic group appears to have fewer problems than the nondiabetic group, however, these subsets are reported as showing "no significant difference."
