Table 1

Characteristics of patients at inclusion.

	Good healers (N=11)	Poor healers (N=11)
Gender (M/F)	7/4	8/3
Age (years)	58 (35-79)	55 (46-65)
Wound surface area (cm^2)	3.5 (0.25-12.5)	6.75 (1.05-31.25)
Wound Duration (months)	4 (1-12)	4 (1-24)
HbA1C (mg%)	7.6 (6.4-9.6)	7.4 (6.8-11.8)
ABi	1.2 (1.1-1.7)	1.18 (0.84-1.48)
MMP-9	0.06 (0.02-0.82)	1.03 (0.12-3.50)

HbA1C: glycated hemoglobin; ABi: ankle brachial index; MMP: matrix metalloproteinase. Values are expressed as median with interquartile range (- percentile).
