Chi square for alcohol withdrawal - comparing CDT ≤ 2.5 with those with CDT > 2.5: Chi square=4.77, p=.029

b

Chi square for alcohol withdrawal- comparing positive BAL vs. negative BAL: Chi square=54.01, p<.001

c

Chi square for alcohol withdrawal - comparing + BAL and/or CDT>2.5: Chi square=33.36, p<.001

d

Chi square for morbidity composite score- comparing positive BAL vs. negative BAL: Chi square= 5.32, p<0.022

e

Chi square for morbidity composite score- comparing positive BAL vs. negative BAL: Chi square= 4.82, p<0.029

There was no statistical relationship between CDT and the morbidity trauma score.

There was no statistical relationship between BAL or CDT levels and length of stay.
