Axons and foot ulcers in the aligned and random nanofiber NGC groups

Item	Aligned scaffold group	Random scaffold group	P-values
Presence of axons (NF200 staining; animals with ulcer/group number)
In nerve guide	7/7	6/7	0.299
In distal nerve	7/7	4/7	0.035
Presence of foot ulcer (animals with ulcer/group number)	0/7	3/7	0.096

P-values are based on Fisher’s method on 2 × 2 cross tabulation (Fisher’s exact test). NGC: Nerve guide conduit; NF200: neurofilament.
