Longitudinal changes in pain relief, functional improvement and blood perfusion restoration. Legend: The assessments of pain were accessed based on a the Wong–Baker Faces Pain Rating Scale, the functional improvement was assessed based on b the pain-free walking time, and blood perfusion restoration was assessed with c the transcutaneous oxygen pressure, d the ankle-brachial index, and e, the toe-brachial index. The values are presented in linear graphs that show the means and SDs. * P < .05 vs. baseline; ** P < .01 vs. baseline. WBFPS, Wong–Baker Faces Pain Rating Scale; PFWT, pain-free walking time; TcPO2, transcutaneous oxygen pressure; ABI, ankle-brachial index; TBI, toe-brachial index; PBMNCs, peripheral blood mononuclear cells; PCCs, purified CD34+ cells
