Receiver operating characteristic curve analysis for optimal cutoff values of laboratory data at diagnosis for the introduction of chemotherapy

Variables	Cutoff	Sensitivity	Specificity	AUC	95% CI
Lymphocyte (cells/μL)	1,710	0.51	0.75	0.64	0.55–0.73
Hemoglobin (g/dL)a	12.2	0.73	0.63	0.70	0.61–0.78
Red cell distribution width (%)a	13.9	0.79	0.53	0.67	0.58–0.77
Sodium (mEq/L)	140	0.58	0.73	0.67	0.58–0.76

Note:

^aThere was a significant inverse correlation between hemoglobin and red cell distribution width (r=–0.31, 95% CI –0.46 to –0.17, P<0.01).

Abbreviations: AUC, area under the curve; CI, confidence interval.
