Table 2.

Odds ratios for significant predictors of mortality (on univariate and multivariate analysis)

Predictors	Crude OR (95% CI)	Adjusted OR (95% CI)
Shock at presentation	10.72 (5.25–21.9)	4.44 (1.72–11.49)
Coma at presentation	19.51 (8.57–44.41)	6.69a (2.52–17.74)
Age >65 years	3.96 (1.46–10.69)	2.52b (0.73–8.64), p = 0.142
Presence of head injuries	7.58 (3.51–16.34)	4.57c (1.95–10.73)
Presence of chest injuries	17.61 (5.90–52.50)	7.96d (2.79–22.68)

Note: p-values are <0.01 unless otherwise stated

^aAdjusted for shock, elderly age and the presence of chest injuries only

^bAdjusted for shock and coma at presentation only

^cAdjusted for shock and presence of chest injuries only. Coma at presentation was not included in the multivariate analysis for head injury because it was on the causal pathway between head injury (exposure) and death (outcome)

^dAdjusted for shock, coma and presence of head injuries only
