Age (years)	18 (2–19)	16 (1–19)	17 (2–19)	14 (2–19)	0.009
Gender (male)	83.3%	62.5%	79.7%	90.5%	0.074
Nationality (UAE national)	77.8%	65.6%	73.4%	71.4%	0.671
ICU admission	22.2%	21.9%	18.8%	19.0%	0.963
Length of hospital stay (days)	3 (1–42)	3 (1–73)	3 (1–70)	2 (1–36)	0.671
Mortality	5.6%	9.4%	1.6%	4.8%	0.279
GCS	15 (3–15)	15 (3–15)	15 (3–15)	15 (3–15)	0.024

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.
