A. Box-and-whiskers plots of wall thickness at the level of ileo-colonic anastomosis according to different Rutgeerts score. The boxes at each score extend from the 25th percentile (x[25]) to the 75th percentile (x[75]) [i.e., the interquartile range (IQ)]; the lines inside the boxes represent the median values. The line emerging from the boxes (i.e., the "whiskers") extend to the upper and lower adjacent values. The upper adjacent value is defined as the largest data point ≤x[75] + 1.5 × IQ, and the lower adjacent value is defined as the smallest data point ≥x[25] - 1.5 × IQ. Observed values more extreme than the adjacent values, if any, are individually plotted (circles). * p < 0.001 score 1 vs score 0, 2-4. The horizontal line indicates the cut-off value of 3.5 mm. B. Box-and-whiskers plots of extension of intramural lesion at the level of neo-terminal ileum according different Rutgeerts score. The boxes at each time unit extend from the 25th percentile (x[25]) to the 75th percentile (x[75]) [i.e., the interquartile range (IQ)]; the lines inside the boxes represent the median values. The line emerging from the boxes (i.e., the "whiskers") extend to the upper and lower adjacent values. The upper adjacent value is defined as the largest data point ≤x[75] + 1.5 × IQ, and the lower adjacent value is defined as the smallest data point ≥x[25] - 1.5 × IQ. Observed values more extreme than the adjacent values, if any, are individually plotted (circles). * p < 0.001 score 1 vs score 4, ** p = 0.03 score 1 vs score 2, *** p = 0.04 score 1 vs score 3
