Cut-off selection of serum Hsp90-beta by ROC curve analysis. A-C. selection of cut-off for serum value of Hsp90-beta in distinguishing lung cancer patients from normal group; receiver operating characteristic curves for Hsp90-beta [area under the curve (auc): 0.976]; D-F. selection of cut-off for serum value of Hsp90-beta in distinguishing lung cancer patients from benign group; receiver operating characteristic curves for Hsp90-beta [area under the curve (auc): 0.920]. ROC, receiver operating characteristic curve; Sens, sensitivity; Spec, specificity.
