Predicted probabilities of having a score of 0 (section A), 1 (section B), and ≥2 (section C) from a polychotomous ordinal logistic model with ICA wall thickness and extension of neo-terminal intramural lesions as covariates. Section A. In absence of intramural lesion (extension 0) of neo-terminal ileum, the predicted probability to have score 0 is > 80% (a) when ICA wall thickness is ≤ 3.5 mm and progressively decreases to < 15% for ICA wall thickness ≥ 8 mm (b). The probability to have score 0 progressively decreases from 75% (c) to 23% (d) for intramural lesions of the neo-terminal ileum increasing from 3 cm to 20 cm. Section B. In absence of intramural lesion (extension 0) of neo-terminal ileum, the predicted probability to have score 1, progressively increases from 23% (a) to 66% (b) for wall thickness of ICA increasing from 3.5 mm to 8 mm. In absence of intramural lesion (extension 0) of neo-terminal ileum, the probability to have score 1 with ICA wall thickness > 9 mm is low (< 50%) (c). When the extension of intramural lesions at the level of neo-terminal ileum increases from 3 to 20 cm, the probability to have score 1 progressively increases from 24% (d) to 66% (e). Section C. In absence of intramural lesion (extension 0) of neo-terminal ileum, the predicted probability to have score ≥2 is < 1% (a) when ICA wall thickness is ≤ 3.5 mm and progressively increases to >80% (b) for ICA wall thickness >10 mm. With ICA wall thickness ≥8 mm and with intramural lesions of the neo-terminal ileum increasing from 3 cm to 20 cm, the probability to have score ≥2 progressively increases from 27% (c) to 80% (d).
