TGFβ is strongly associated with the presence of collagen I. IHC values for each granuloma were plotted against one another to assess association between collagen I, TGFβ signaling, and M2 macrophages. Values were transformed, and Pearson’s test for parametric correlation was used to determine significance. Significant correlations are denoted by red symbols. Open circles are significant but r < 0.7, while asterisks indicate that r > 0.7
