Pro-motility Preparation Protocol May Reduce the Rates of Failed Patency Capsule Among Patients with Crohn's Disease in Clinical Remission.

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
backgroundPatency capsule (PC) ingestion is commonly used to minimize capsule retention in high-risk patients with Crohn's disease (CD). However, false-positive rates remain high, precluding the use of video capsule endoscopy (VCE). We aimed to compare the efficacy of two preparation protocols in reducing failed PC rates in patients with CD.
methodsThis bi-center retrospective case-control study included adult patients with small-bowel CD in clinical remission who underwent PC ingestion. The pro-motility group followed a low-residue diet, then a clear fluid diet, and took bisacodyl after ingestion, while the control group followed only a clear fluid diet. The primary outcome was failed PC, defined as the absence of PC excretion or presence on abdominal X-ray at 30 h post-ingestion. Multivariable logistic regression was used to identify predictors of failed PC.
resultsAmong 273 patients (83 in the pro-motility group, 190 controls), the pro-motility group was older (median 36 [27-48] vs. 31 [24-43], p = 0.012) and had a lower rate of B2/3 disease phenotype (32.5 vs. 53.1%, p = 0.002) compared to controls. The pro-motility group also had a lower failed PC rate (12.0 vs. 24.7%, p = 0.023). Longer disease duration (adjusted odds ratio (AOR) 1.053, 95% confidence interval (CI) 1.016-1.091, p = 0.005) increased the odds of failed PC, while the pro-motility protocol was protective (AOR 0.438, 95% CI 0.200-0.956, p = 0.038), outweighing the influence of B2/3 disease phenotype (AOR 1.743, 95% CI 0.912-3.332, p = 0.093).
conclusionsThe pro-motility preparation protocol could substantially improve the success rates of the small-bowel patency test in patients with CD undergoing PC ingestion, potentially reducing the risk of capsule retention and associated complications.
