Area under the curve at the time of admission

Test result variable(s)	Area	Std. errora	Asymptotic sig.b	Asymptotic 95% confidence interval
				Lower bound	Upper bound
GCS (Admission)	0.121	0.032	0.000	0.057	0.185
ISS (Admission)	0.684	0.038	0.000	0.610	0.759
RTS (Admission)	0.159	0.034	0.000	0.093	0.226
TRISS (Admission)	0.188	0.031	0.000	0.128	0.248
APACHE II (Admission)	0.913	0.024	0.000	0.867	0.960

^aUnder the nonparametric assumption; ^bNull hypothesis: true area = 0.5. The test result variable(s): GCS (Admission), ISS (Admission), RTS (Admission), TRISS (Admission), APACHE II (Admission) has at least one tie between the positive actual state group and the negative actual state group.
