ROC analysis results of the RDW–SD and RDW–CV in predicting aortic valve calcification.

Characteristics	Area under curve	95% CI	p-value	Bounpoint (cut off point)	Sensibility	Specificity
RDW–SD	0.594	0.559–0.629	0.001	43.8	0.399	0.770
RDW–CV	0.579	0.544–0.614	0.001	12.9	0.472	0.664

RDW–SD, red cell distribution width–standard deviation; RDW–CV, red cell distribution width–coefficient of variation; ROC, receiver operating characteristic.
