Correlations for the percent area of expression for each inflammatory factor and the number of macrophages in each tissue section (n = 30) revealed the CD68+ macrophage number correlated with (A) TNFα and IL-1ß and (B) VEGF but not PDGFbb. There was also a correlation for CD68+ cells with (C) NGF and substance P. Data are presented as median ± SD. The circles and stars represent the outliers and extremes, respectively.
