Fecal Burden on CT Weakly Correlates with Bowel Function in Adults and is Poorly Associated with Clinical Symptoms.

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
introductionGI symptoms are frequently non-specific and common across many disorders. Fecal burden on CT imaging is a finding commonly reported on, but with an undefined relationship to GI symptoms. A study was performed to assess the association between fecal burden and GI function and symptoms.
methodsA single-center cross-sectional study was performed assessing the relationship between fecal burden using the Starreveld scoring method for patients undergoing CT Abdomen/Pelvis for any indication, and GI function and symptoms using a survey tool with a validated GI symptom scale.
results205 patients completed surveys on the day of CT exam. Interobserver reliability for fecal burden assessment yielded kappa of 0.6. Spearman correlation showed a negative correlation between total colon fecal burden and stool frequency (rho = - .21, p = .002), liquid bowel movements (rho = - .23, p < .001), and bloating (rho = - .16, p = .02). Positive correlation was identified with difficult stool evacuation (rho = .18; p = .009). No correlation was found for symptoms of hard stools, urgency, fullness, satiety, abdominal discomfort, abdominal pain, or nausea. Logistic regression analysis demonstrated total colon fecal burden distinguished symptom frequency for symptoms of difficulty evacuating (OR 1.12, p = .05) and liquid bowel movements (OR 0.8, p < .001) only.
conclusionFecal burden on CT imaging is weakly associated with metrics of bowel function and poorly associated with GI symptoms other than difficulty evacuating. This study challenges the practice of attributing GI symptoms to fecal burden beyond those for which there is any identified association.
