Cytokine R/Rho P
Protein -0.1174 n.s.
Aggrecan -0.1256 n.s.
BMP-2 0.5537 <0.001
BMP-7 0.0307 n.s.
IL-1β 0.0567 n.s.

  1. Overview about the correlation strength between the changes of the IKDC Score evaluated initially and after 1 year with initial intraarticular cytokine levels of BMP-2, BMP-7, IL-1β, bFGF, IGF-I, aggrecan and the total protein content. The only statistically significant correlation was found in case of BMP-2 (R-Pearson coefficient, Rho Spearmen coefficient).
