Low skeletal muscle density is a risk factor for constipation in patients on maintenance dialysis.

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
Background: Constipation is among the most common gastrointestinal disorders among dialysis patients. Low skeletal muscle density (SMD), a marker of increased intramuscular fat infiltration in muscle, is also among the important characteristics of dialysis patients. This study aimed to assess whether a low SMD is associated with constipation in patients on maintenance dialysis. Methods: A total of 428 dialysis patients from three dialysis centers in our hospital were enrolled in this cross-sectional study. Constipation was assessed according to the Rome IV diagnostic criteria. The SMD was determined via computed tomography (CT) at the first lumbar vertebra level. Univariate and multivariate logistic regression analyses were used to explore the potential effect of SMD on constipation. Results: The mean age of all participants was 56.09 (±15.17) years. The percentage of male participants was 42.99%. In accordance with the Rome IV diagnostic criteria, the prevalence of constipation among dialysis patients was 62.62%. We found that compared with that of patients with no constipation, the SMD of patients with constipation was significantly lower [31.70 (±7.33) HU vs. 38.44 (±6.44) HU, P < 0.001]. Decreased SMD was significantly associated with constipation in dialysis patients. The association remained statistically significant even after adjusting for age, dialysis vintage, hemoglobin concentration, serum phosphate concentration and history of diabetes, skeletal muscle index and body mass index. The odds ratios were 0.26 (0.10-0.70), 0.25 (0.08-0.80) and 0.21 (0.05-0.80) for SMD quartile 2, quartile 3 and quartile 4, respectively (reference, quartile 1). Furthermore, the area under the curve (AUC) of the nomogram in the training group was 0.74, whereas that in the test group was 0.76. Conclusion: Dialysis patients have a high prevalence of constipation. We found that a low SMD is an independent risk factor for constipation. Our findings provide a new perspective on the causes of susceptibility to constipation among dialysis patients.
