Impacts of stem cells from different sources on wound healing rate in diabetic foot ulcers: a systematic review and meta-analysis.

In the group with a follow-up time of 3 months or less, peripheral blood stem cells demonstrated the most favorable therapeutic effect (OR = 7.54, 95% CI: 2.88–19.77), though it did not reach statistical significance (P > 0.05), while umbilical cord stem cell therapy had statistically significant efficacy (P < 0.05), despite higher heterogeneity (I 2 = 88.37%).
