Furthermore, patients with PAD show statistically significant differences for HbO 2 before and after treatment (0.022±0.004 before, 0.036±0.006 after, P=0.029), while the change in THb before and after treatment is marginally significant or (0.045±0.006 before, 0.067±0.009 after, P=0.057) and the corresponding change in SO 2 is non-significant (P=0.287).
