Altered pattern of tumor necrosis factor-alpha production in peripheral blood monocytes from Crohn's disease

Figure 3 Correlation of disease activity index with monocyte expression of tumor necrosis factor-alpha in inflammatory bowel disease patients. Correlation of activity index, expressed by PCDAI (Pediatric Crohn’s disease Activity Index) or PUCAI (Pediatric Ulcerative Colitis Activity Index) with monocyte expression of TNF-α in patients suffering from Crohn’s disease (CD) and ulcerative colitis (UC). The squared Pearson correlation coefficients (R²) are shown.
