Fig. 2. — Comparison of the emergency department (ED) length of stay (LOS) between the alcohol-unrelated group and alcohol-related group by mechanism of injury. The lower and upper boundaries of each box represent the 25th and 75th percentiles, the bar within each box represents the median, and the whiskers extend to the most extreme observation within 1.5 interquartile range units of the 25th and 75th quartiles. There were significant differences between the alcohol-unrelated group and alcohol-related group in all mechanisms of injury.
