Summary

This study tested whether antimicrobial photodynamic therapy (aPDT) can improve wound healing in people with diabetic foot ulcers. Researchers compared wound quality and repair in 94 participants who received either aPDT or a placebo. The goal was to see if this light-based treatment could speed up healing and reduce wound severity.
