Diffusion-weighted imaging to predict longer-term response in Crohn's disease patients commencing biological therapy: results from the MOTILITY trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPredicting longer-term response to biological therapy for small bowel Crohn's disease (SBCD) is an unmet clinical need. Diffusion-weighted magnetic resonance (MR) imaging (DWI) may indicate disease activity, but its predictive ability, if any, is unknown. We investigated the prognostic value of DWI for 1 year response or remission (RoR) in SBCD patients commencing biologic therapy, including incremental value over C-reactive protein (CRP) and faecal calprotectin (FC).
methodsA subset of participants in a prospective, multicentre study investigating the predictive ability of motility MRI for 1-year RoR in patients starting biologic therapy for active SBCD, underwent additional DWI at baseline and post-induction (12-30 weeks). CRP and FC were collected in a subgroup. RoR at 1 year was evaluated using clinical and morphological MR enterography (MRE) parameters. We calculated sensitivity and specificity to predict RoR and quality of life (QoL) at 1 year, comparing apparent diffusion coefficient (ADC) value, Clermont score, and CRP using multivariable logistic regression.
resultsA total of 25 participants were included (mean 36.9 years, 32% female). ADC changes and Clermont score had poor sensitivity (30.0% [95% CI, 6.7-65.2] and 40.0% [95% CI, 12.2-73.8], respectively) and poor-to-modest specificity (50.0 [95% CI, 27.2-72.8] and 65.0% [95% CI, 40.8-84.6]) for RoR. None of Clermont score, CRP, or FC predicted QoL.
conclusionsDWI has inadequate sensitivity and specificity for RoR at 1 year. There is no significant incremental prognostic value of DWI over CRP and FC to predict RoR and/or QoL at 1 year. ADVANCES IN KNOWLEDGE: Early post-induction DWI has no prognostic value for RoR at 1 year.
