Pre-treatment serum concentration and urinary excretion of MIF in patients with proliferative and non-proliferative glomerulonephritis (GN)

		Serum MIF (ng/ml)	Urinary MIF (ng/mg Cr)
Proliferative GN	Mean ± SD	2.2 ± 1.0	4.2 ± 2.1
	Median (range)	1.9 (1.1–3.4)	3.6a,b (2.0–8.1)
Non-proliferative GN	Mean ± SD	1.8 ± 0.3	3.0 ± 1.9
	Median (range)	1.3 (1.0–2.4)	2.2c (1.7–4.3)
Pooled	Mean ± SD	1.7 ± 0.8	3.7 ± 1.9
	Median (range)	1.7 (1.0–3.3)	3.2 (1.7–8.1)
Healthy	Mean ± SD	0.2 ± 0.01	0.5 ± 0.02
	Median (range)	0.2 (0.18–0.21)	0.5 (0.4–0.5)

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