Table 2. Receiver operating characteristics analyses of platelet volume indices in breast cancer patients.

Variables	Cut-off value	AUC (95%CI)	Specificity	Sensitivity
PDW	15.3	0.61 (0.47–0.74)	0.85	0.4
MPV	9.0	0.62 (0.49–0.76)	0.79	0.48
PDW/P	0.59	0.58 (0.46–0.7)	0.64	0.6
MPV/P	0.35	0.56 (0.41–0.7)	0.79	0.4

Abbreviations: AUC, area under the curve; PDW, platelet distribution width; MPV, mean platelet volume; PDW/PLT, platelet distribution width to platelet count ratio; MPV/PLT, mean platelet volume to platelet count ratio; CI, confidence interval.
