CI = confidence interval; FIM = Functional Independence Measure; LOSE = length of stay efficiency; TBSA = total burn surface area.

^*Interaction between FIM cognitive and age.

^†Community discharge model; uses an odds ratio.

^‡TBSA <10% (note that these are deciles: 0 is <10%, 1 is 10%-19%, etc).
