Nerve diameters of the experimental and control groups

Experimental groups			Non-operated group
Group I-Saline d I [mm]	Group II-HA d II [mm]	Group III-FK-506 d III [mm]	Control dC [mm]	P valuea
				<0.051

Nerve diameters:

¹ P value for the control group compared to all three experimental groups;

² P value for the saline group compared to both the HA and FK-506 groups;

³ P value for the HA group compared to the FK-506 group.

^aA P value <0.05 was considered statistically significant.
