borderline significantP = 0.07
In patients with AAV, U-DKK-3/Cr correlated with sCr ( r = 0.72, P < 0.001), but there was only a borderline significant correlation with the extent of fibrosis ( r = 0.30, P = 0.07; Table 2 ), and there was a correlation between S-DKK-3 and the extent of fibrosis ( r = 0.36, P < 0.05; Table 2 ), but not with sCr ( r = 0.27, P = 0.07).
