None of the provided content of the article entitled "Commentary: Efficacy of stem cell therapy for diabetic kidney disease: a systematic review and meta-analysis" contains verified facts about the effectiveness of stem cell therapy. Available search results describe other meta-analyses on diabetic nephropathy, such as a prevalence of 35.3% (95% CI 27.46–43.14) in sub-Saharan Africa[2] or a positive predictive value of 49.2% (95% CI 43.8–54.5) for the combination of NDRD and mixed forms at biopsy[1]. These studies are not talking about cell therapy. Without the original text of the article, it is not possible to create a summary.
