Effect of age of onset at diagnosis of CD and NOD2 variants on treatment. Th age of onset of CD in 202 patient with NOD2 variant (grey bars) or wild-type (white bars) alleles is compared regarding steroid-dependent or refractory course of disease (A), need for long-term immunosuppressive therapy with azathioprine (AZA) and methotrexate (MTX) (B) or anti-TNFɑ agents (C). Differences were compared using Kruskal-Wallis test. A p-value below ≤0.05 was considered to be significant and indicated with an asterix.
