Letter to Editor Regarding “Mean Platelet Volume-to-Lymphocyte Ratio is a Biomarker of 1-Year Mortality in Patients With Diabetic Foot Infections”

We read with great interest the prospective observational study of Aragón-Sánchez et al. They reported that the increase in the mean platelet volume (MPV) to lymphocyte ratio (MPVLR) value is a biomarker accompanying 1-year mortality in patients with a diabetic foot infection. We explained why the MPV value and associated MPVLR value may not be a prognostic biomarker of mortality in patients with diabetic foot infections.
