Table II. Potential factors contributing to hypernatremia. Comparing burn injury patients to the non-burn injury data of Hoorn et al. (7). Patients with hypernatremic episodes above 150 mmol/l were defined as “cases”, patients without hypernatremic episodes as “controls”.

The Fisher Exact Test was used for all nominal variables. For all other variables the Mann-Whitney U-test was used. A p-value <0.05 was considered as significant. Significant p-values are shown in bold.
