FBG: fasting blood glucose, HbA1c: glycosylated hemoglobin, CRP: C reactive protein, WBC: white blood cells, Alb: albumin, ABI: Ankle/Brachial Index, NPWT: negative pressure wound therapy, Mean difference: difference (intervention-control) is shown for mean changes from baseline (D6-D0). Analysis of covariance analysis was used to compare the difference of change from baseline between the 2 groups with the baseline value as a covariate, p<0.0083 was deemed significant.
