Figure 1 Levels of IL-17 (A) and IL-8 (B) secreted in organ cultures of biopsies from H pylori-positive (closed circle) and -negative (open circle) patients. The bar indicates the median value for each group. A: ^aP<0.0005 a vs b, ^bP<0.0001 a vs c, ^cP<0.0005 b vs c,^dP<0.0001 a vs d, ^eP<0.0005 c vs d; B: ^aP<0.0005 a vs b, ^bP<0.0001 a vs c, ^cP<0.0005 a vs d, ^dP<0.0001 a vs d (NS:not significant).
