Immunostaining patterns of IgA in the two groups

	IgA-IgG group (n = 29)	IgA group (n = 28)	P value
Immunofluorescence intensity			0.029*
Grade 1	1 (3.4 %)	8 (28.6 %)
Grade 2	16 (55.2 %)	16 (57.1 %)
Grade 3	12 (41.4 %)	4 (14.3 %)
Location of glomerular deposits			0.014*
Mesangial-only	12 (41.4 %)	25 (89.3 %)
Capillary wall + mesangial	17 (58.6 %)	3 (10.7 %)

Data represent the number (percent) of patients. The chi-squared test was used to compare the distribution of immunofluorescence intensity. Fisher’s exact test was used to compare the proportion of the locations of glomerular deposits
