Area Under ROC curve.

Test result variable(s)	Area	Std. Error^a	Asymptotic sig.^b	Asymptotic 95% confidence interval
				Lower bound	Upper bound
PDW(fl)	.862	.040	.001	.784	.941
MPV (fl)	.816	.044	.001	.730	.903
CRP mg/L	.675	.050	.002	.577	.772
RDW-CV (%)	.760	.042	.001	.678	.842
ESR mm/1st hour	.596	.054	.092	.490	.701

The test result variable(s): PDW (fl), MPV (fl), CRP mg/L, RDW-CV (%), ESR mm/1st hour has at least one tie between the positive actual state group and the negative actual state group. Statistics may be biased. a. Under the nonparametric assumption. b. Null hypothesis: true area =0.5.
