BACKGROUND In response to growth in cardiac imaging, medical societies have published appropriateness use criteria (AUC) and payers have introduced preauthorization mandates, largely through radiology benefits managers (RBM). The correlation of algorithms used to determine preauthorization with the AUC is unknown. In addition, studies applying the 2007 AUC for transthoracic echocardiography rev...

When examining stress effects on coagulation, arithmetic correction is typically used to adjust for concomitant hemoconcentration but may be inappropriate for coagulation activity assays. We examined a new physiologically relevant method of correcting for stress-hemoconcentration. Blood was drawn from healthy men (N = 40) during baseline, mental stress, and recovery, and factor VII activity (FV...

Predictive accuracy has been widely used as the main criterion for comparing the predictive ability of classiication systems (such as C4.5, neural networks, and Naive Bayes). Most of these classiiers also produce probability estimations of the classiication, but they are completely ignored in the accuracy measure. This is often taken for granted because both training and testing sets only provi...
