Multivariate logistic regression analysis for mortality with Acute Kidney Injury Network stage as the AKI variable in the subgroup with ≥20% burn injury

VariableOdds Ratio for Hospital Mortality (95% CI)aP Value
Age (yr)1.13 (1.04–1.22)0.003

  • CI, confidence interval; ARDS, acute respiratory distress syndrome; ALI, acute lung injury; TBSA, total body surface area burned; AKIN, Acute Kidney Injury Network.

  • a Odds ratios for age and percentage TBSA reflect per-year increase in age and per 1% increase in percentage TBSA, respectively.

  • b Compared with no AKI by Acute Kidney Injury Network criteria.
