Definitions: The PEDIS (Perfusion, Extent, Depth, Infection, Sensation) classification developed by the International Working Group of the Diabetic Foot (IWGDF) is a universally accepted classification system developed primarily for DFI research [11]. The PEDIS classification ranges from 1 to 4, ascending with severity, with the suffix O denoting osteomyelitis. A PEDIS score of 1 represents a foot ulcer of no infection, whilst a PEDIS score of 4 represents a severe infection with signs of a systemic response
