Demographic and severity variables by car crash mechanism, Al Ain, 2006–2007 (n = 245).

p = Fisher’s Exact test or Mann Whitney test as appropriate; ICU = Intensive Care Unit, GCS = Glasgow Coma Scale, TRS = Revised Trauma Scale, ISS = Injury Severity Score. Data are presented as number (%) or median (range) as appropriate; Mean (SD) of GCS was 13.31(3.39); 13.1(3.65); 14.27(2.42); 13.81(3.25) in front impact; side angle impact; rollover and other mechanisms respectively. Data are shown as median (range) in the table. Mann-Whitney test uses the ranks for analysis and that is why there is statistical significance between groups despite all groups have the same median range.
