Table 2. Several histological parameters in MN cases with or without FSGS lesion.

	MN with	MN without	P
	FSGS lesion	FSGS lesion
VEGF expression (index)**	1.2 ± 0.7	1.4 ± 0.9	0.6
global sclerotic glomeruli (%)*	11.4 ± 10.8	7.2 ± 7.1	0.1
interstitial fibrosis (index)**	1.2 ± 0.5	1.0 ± 0.6	0.06
arteriosclerosis (index)**	1.7 ± 0.8	1.8 ± 0.7	0.82

* Student’s t-test

** Mann-Whitney U test

Staining intensity of VEGF based on immunohistochemical study was scored semiquantitatively (see Materials and Methods).

Interstitial fibrosis and arteriosclerosis were also graded semiquantitatively (see Materials and Methods).
