The Characteristics and Significance of Locally Infiltrating B Cells in Lupus Nephritis and Their Association with Local BAFF Expression

Table 3

Association between B-cell infiltration and BAFF expression.

	B-cell infiltration
	Grade 0; (𝑛=27)	Grade 1; (𝑛=23)	Grade 2; (𝑛=12)
Intrarenal BAFF staining	—	—	—
No staining	24	7	1
Mild staining	2	9	5
Moderate to intense staining	1	7	6

B-cell infiltration was strongly associated with BAFF expression in the intrarenal region (𝑟=0.6226,𝑃<0.0001).
