Compared to control groups, the CD34<sup>+</sup>MCT was associated with lower total amputation (odds ratio (OR): 0.45, p=0.01; 95% confidence interval (CI): 0.24-0.85) and a higher complete ulcer healing rate (OR: 2.80, p=0.008; 95% CI: 1.31-6.02), but showed no advantage in major amputation (OR: 0.58, p=0.11; 95% CI: 0.29-1.14) and all-cause mortality (OR: 0.82, p=0.62; 95% CI: 0.36-1.83) .
