Figure 2. Changes in EPCs measurements during the four study visits between the patients who did not heal their ulcers (NH) and those who did (H).

There were no differences in all EPC measurements at baseline but patients who healed their ulcers had lower CD34⁺KDR⁺ counts at visits 3 and 4 and CD34⁺CD133⁺ at visit 4. Data are presented as the median and interquartile range box.
