  • a DPC, delayed primary closure; FTSG, full-thickness skin graft; IQR, interquartile range; LRMC, Landstuhl Regional Medical Center; MDRO, multidrug-resistant organism; MTF, military treatment facility; OR, operating room; STSG, split-thickness skin graft.

  • b IFI, invasive fungal wound infection.

  • c P value 1: compares IFI case wounds and non-IFI wounds with SSTIs.

  • d P value 2: compares non-IFI wounds with and without SSTIs.

  • e NA, not applicable.

  • f Two non-IFI wounds with SSTIs were missing the time to wound closure data.

  • g Two fungus-infected wounds, 7 non-IFI wounds with SSTIs, and 8 non-IFI wounds without SSTIs were missing type of closure data.

  • h Operative procedures occurred at the U.S. MTFs.
