Immunogenetic phenotypes in inflammatory bowel disease

Figure 1 The frequency of disease behavior. The test for trend demonstrated a positive linear trend in the frequency of patients with IP and/or S disease as the number of positive immune responses toward I2, OmpC, ASCA and CBir1 increased (P = 0.002). The odds ratios (OR) reflect the odds of having internal penetrating and/or stricturing disease when positive for any 1, combination of 2, 3 or all 4 immune responses, as compared to those patients negative for all immune responses (baseline group).
