Impact of the Body Mass on Complications and Outcome in Multiple Trauma Patients: What Does the Weight Weigh?

Table 5

Multivariate regression analysis referring to MODS analyzing BMI, injury severity (ISS), and APACHE II score as potential predictors.

Predictor	Regression coefficient	Odds ratio (OR)	95% confidence interval (95%-CI)	P value
Underweight	0.254	1.289	0.152–10.9666	0.816
Overweight	0.606	1.832	0.718–4.675	0.205
Obesity	1.437	4.209	1.515–11.692	0.006
Injury severity (ISS)	0.053	1.054	1.020–1.089	0.001
APACHE II	0.058	1.059	1.001–1.121	0.047
Constant	−5.935	—	—	<0.001

BMI group II (normal weight) was set as a categorical reference group for regression analysis between the BMI groups.
