Comparison of the endoneurial toluidine blue-stained area

		Epi-perineurium removal group
Group (n = 3)	Sham group	day 2	day 7	day 20	day 42
% area	78.0 ± 0.04	55.3 ± 0.09*	49.3 ± 0.02*	39.3 ± 0.16*	53.7 ± 0.25

Data are expressed as mean ± SD. Units are percentages. At days 2, 7, and 20 in the epi-perineurium removal group, the percentage area of toluidine blue staining in the endoneurium was significantly different from the sham group.

^*Significantly different from the sham group (P < 0.05).
