Motility index measured by magnetic resonance enterography is associated with sex and mural thickness

-#- means that standard deviation not given due to small number of patients. Values of motility index measured as arbitrary units are presented as mean ± SD. Differences between the diseases were calculated by ANOVA. Differences between sexes in each disease group were analyzed by Student’s t-test. After Bonferroni correction, differences were found between healthy controls and other diseases in MI of jejunum (P = 0.043) and terminal ileum (P = 0.059). P < 0.05 was considered statistically significant.
