Autologous Stem Cell Therapy in Critical Limb Ischemia: A Meta-Analysis of Randomized Controlled Trials

Figure 3

Forest plot of meta-analysis of ulcer healing in cell therapy and standard care for critical limb ischemia. (a) Subgroup analyses of bone marrow stem cells (BMSCs) versus peripheral blood stem cells (PBSCs). (b) Subgroup analyses among high dose (10⁹), medium dose (10⁸), and low dose (10⁷). Squares indicate the risk ratio, and horizontal lines represent 95% confidence intervals.
