Table 4.

Pre-treatment serum concentration and urinary excretion of MIF in patients with proliferative and non-proliferative glomerulonephritis (GN) after division into Responders (R) and Non-Responders (NR) subgroups

		Serum MIF (ng/ml)		Urinary MIF (ng/mg Cr)
		Mean ± SD	Median (range)	Mean ± SD	Median (range)
Proliferative GN	R	1.3 ± 0.8	1.4 (1.1–1.5)	2.1 ± 1.3	2.4 (2.0–3.7)
	NR	3.3 ± 1.2	3.0 (2.0–3.4)	5.9 ± 2.9	6.1a,b,c (2.9–8.1)
Non-proliferative GN	R	1.7 ± 0.2	1.8 (1.0–2.0)	2.9 ± 1.8	2.2 (1.7–4.1)
	NR	2.0 ± 0.4	1.9 (1.2–2.4)	3.1 ± 2.1	2.3 (1.9–4.3)

Differences were considered significant for P < 0.05 (Kruskal-Wallis ANOVA)
