Effects of Photobiomodulation Therapy on the Expression of Hypoxic Inducible Factor, Vascular Endothelial Growth Factor, and Its Specific Receptor: A Randomized Control Trial in Patients with Diabetic Foot Ulcer

What the authors concluded

Following the intervention, the results revealed that the PBM group had significantly lower levels of VEGF than the placebo group (p = 0.005). The %DWSA was significantly higher in the PBM group compared to the placebo group (p = 0.003). Moreover, VEGF showed a significant negative correlation with %DWSA (p < 0.001)." Note: DWSA = decrease in the wound surface area
