The Effect of Alcohol Intoxication on Mortality of Blunt Head Injury

Table 3

The comparisons of BAC levels by mortality and ISS (𝑛=3628).

	Mortality (𝑛=141/3628) (𝑃^#<0.001)	ISS (𝑃^∗<0.001)
BAC (mg/dL)
Less than 8	3.7% (123/3296)	8.77 ± 7.66
8 to less than 100	9.8% (4/41)	14.10 ± 8.52
100 to less than 230	4.5% (9/165)	13.05 ± 9.77
≥230	5.4% (5/126)	11.37 ± 8.47

𝑃^#: Chi-square. There is a statistical significant difference of mortality among BAC levels. 𝑃^∗: one-way analysis of variance. There is a statistical significant difference of ISS among BAC levels.
