In this issue of the Archives, Fine and colleagues1 report a major validation of clinical prediction rules for predicting group A streptococcal (GAS) pharyngitis. They examine the prediction model that I and my research team2 first reported in 1981 and the modification (incorporating age into the decision rule) that McIsaac et al3 reported in 1998. This validation confirms a recent meta-analysis that arrived at the same finding.4
