Receiver operating characteristic curve analyses of red cell distribution width and red cell distribution width to platelet count ratio in breast cancer patients.

Characteristics	Optimal cut-off point	Specificity	Sensitivity	AUC (95%CI)
PDW/P	0.59	0.67	0.58	0.59 (0.47–0.72)
RDW	13.7	0.73	0.39	0.55 (0.44–0.67)
RPR	0.71	0.77	0.42	0.52 (0.38–0.65)

Abbreviations: AUC, area under the curve; PDW/P, platelet distribution width to platelet count ratio; RDW, red cell distribution width; RPR, red cell distribution width to platelet count ratio; CI, confidence interval.
