Association between Crohn's disease and pulmonary nodule patterns: an inverse probability-weighted analysis of real-world data.

New evidenceCrohn's diseasebiologicsepidemiology
Clinical takeawayNo change in practice: manage incidental nodules by standard radiology criteria. Nodule burden in CD rose with age, not with disease phenotype or extraintestinal manifestations; adalimumab correlated with fewer non-solid and 6-8 mm nodules, an observational association of unclear meaning.
What it foundCD patients had higher pulmonary nodule counts (solid nodules IRR 1.80, 95% CI 1.62-1.98) and adalimumab correlated with fewer non-solid and 6-8 mm nodules (IRR 0.615-0.676).
ContextConfirms CD's systemic impact on pulmonary nodules in adults but challenges the utility of disease phenotype for risk stratification, shifting focus to age and medication exposures. Findings are based on a retrospective multicenter cohort study of 2,009 CD patients and 4,002 controls.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
