Area under curve at 48 hours after admission

Test result variable(s)	Area	Std. errora	Asymptotic sig.b	Asymptotic 95% confidence interval
				Lower bound	Upper bound
GCS (Day 2)	0.056	0.023	0.000	0.011	0.101
ISS (Day 2)	0.684	0.038	0.000	0.610	0.759
TRS (Day 2)	0.036	0.018	0.000	0.001	0.071
TRISS (Day 2)	0.116	0.022	0.000	0.072	0.159
APACHE (Day 2)	0.965	0.012	0.000	0.941	0.990

^aUnder the nonparametric assumption; ^bNull hypothesis: true area = 0.5. The test result variable(s): GCS (Day 2), ISS (Day 2), TRS (Day 2), TRISS (Day 2), APACHE (Day 2) has at least one tie between the positive actual state group and the negative actual state group. Statistics may be biased
