AMI = acute myocardial infarction. | ||||
c = “c” statistic corresponding to the area under the receiver operating characteristics (ROC) curve. Statistic values >0.7 indicate the model discriminates well; value of 0.5 indicates discrimination no better than chance. | ||||
A p value of >0.05 indicates the model provides a good fit for the data (Hosmer-Lemeshow goodness of fit test). | ||||
