ASCS autologous skin cell suspension, NBR National Burn Repository, STSG split-thickness skin graft alone, TBSA total body surface area
aIncludes both ASCS ± STSG and STSG alone patients
bPatients with TBSA >50% were included in the original dataset but were not considered for matching in the current analysis due to labeling for ASCS at the time of the study (see Methods)
