We report the global pattern of ileal gene expression in a cohort of 359 treatment-naïve pediatric Crohn Disease, Ulcerative Colitis patients and controls. We focus on genes with consistent altered expression in inflamed and unaffected ileum of CD [ileal-involved CD (iCD) and non-invloved ileal CD (cCD)], but not in the ileum of ulcerative colitis or control.

How this grade was computed
Weighted mean of 4 scored metric(s) → 95/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published bulk-RNA-seq thresholds, weighted by its importance; nothing is hidden or subjective.
