Short-term complications of extremity war wounds with respect to adjuvant hyperbaric oxygen (HBO) therapy and adjustment for North Atlantic Treaty Organization (NATO) strategy of emergency war surgery in Group I of patients treated at the Split University Hospital between 1991 and 1995*

*Group I is described in Table 2.

†Odds ratio (OR) with 95% confidence intervals (95% CI) for short term complications of war wounds when HBO therapy was not applied and when it was applied. The adjustment for use of NATO surgical strategy was performed by multiple logistic regression, with HBO therapy and NATO surgical strategy as the binary independent variables.
