Wound Fluid Matrix Metalloproteinase-9 as a Potential Predictive Marker for the Poor Healing Outcome in Diabetic Foot Ulcers

Figure 3

The MMP-9 is a predictive factor for diabetic ulcer wound healing outcome. The ROC analysis gives an area under the curve of 0.90(0.6–1.04). The MMP-9 level of 0.3805 at week 0 has a sensitivity of 81.8% and a specificity of 64.6% for detecting a wound area reduction of less than 50% at week 4.
