  1. Showed optimal cut-off points and related diagnostic value by ROC analysis with related sensitivity, specificity, AUC, and p value (LAV = left atrial volume; LVESV = left ventricular end systolic volume; LVEDV = left ventricular end diastolic volume; AUC = area under the curve). Larger AUC indicated better diagnostic value.
