Size distribution of VGF-positive neurons after SNL

	Small/medium (diameter <25 μm), of total	VGF+ neurons,% of small/medium	Large (diameter >25 μm), % of total	VGF+ % of large
L5
Day 1	78.2 ± 2.1	86 ± 1.6*	22.4 ± 2.3	59.8 ± 5.8***
Day 7	76.9 ± 3.5	64.6 ± 3.3*	20.8 ± 3.9	75.8 ± 3.1***
L4
Day 1	65.9 ± 1.8	65.1 ± 5.9**	34.7 ± 1.5	40.8 ± 3.3
Day 7	65.8 ± 3.7	40.3 ± 3.9**	36.5 ± 4.6	30.2 ± 7

The percentage of small/medium and large VGF-positive neurons in L5 and L4 DRG was compared between day 1 and day 7. At day 7, there was a significant decrease in the number of small/medium VGF-positive neurons in both L5 (*p < 0.005, t test) and

L4 (**p < 0.05, t test) DRG.

The number of large VGF-positive neurons at day 7 was significantly increased (***p < 0.05, one-tailed t test) in L5 DRG and decreased in L4 DRG.
