The P value was calculated by checking the difference in the distribution of different variables between the two identified groups (i.e., Crohn's disease and ulcerative colitis).
2
The Chi-square test or Fisher’s exact test was employed for evaluation.
BMI: Body mass index; COPD: Chronic obstructive pulmonary disease. Data are expressed for continuous variables as median (interquartile range) and, for categorical and ordinal variables, as numerosity (%). Significant P values are indicated in bold.
