Test result variable	Area	Standard error^a	Asymptotic significance^b	Lower limit	Upper limit
COX-2	0.703	0.085	0.028	0.536	0.869
VEGF	0.678	0.086	0.055	0.508	0.847
Ki67	0.673	0.086	0.062	0.504	0.841
COX-2 + VEGF + Ki67	0.741	0.081	0.009	0.582	0.901

The test result variable COX-2, VEGF, Ki67, COX-2 + VEGF + Ki67 has at least one binding value between the positive actual state group and the negative actual state group. There may be a deviation in the statistics
^aAccording to the nonparametric assumption; ^bOriginal hypothesis: true are = 0.5
