Fig. 2

Relationship between microcalcifications or expression levels of CD68, CD163, BMP-2 and patients’ DFS. A shows that patients with microcalcifications were correlated with poor DFS (p = 0.010). B and C show that the high expressions of CD163 and BMP-2 were significantly correlated with poor DFS (P = 0.003, and 0.000, respectively). D shows Expression of CD68 was not correlated with prognosis with a P value of 0.215
