Fig 4. Correlation of urinary activin A level with histological changes in kidney biopsy specimens.

Fig 4

A: Urinary activin A levels in patients with renal AAV with (+; n = 11) and without (-; n = 3) cellular crescentic glomeruli. *p<0.05. B: Urinary activin A levels in patients with renal AAV with (n = 9) and without (n = 5) sclerotic glomeruli. N.S., not significant. C, D: Urinary activin A levels in patients with renal AAV with interstitial injuries (grade 1–3) (C) and interstitial cell infiltration (grade 1–3) (D). E: Urinary activin A levels in patients with renal AAV with more than (n = 8) and less than (n = 6) three CD68-positive cells per selected field. *p<0.05. F: Urinary activin A levels in patients with renal AAV with more than (n = 7) and less than (n = 7) nine CD163-positive cells per selected field. *p<0.05.
