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
objectiveTo evaluate the feasibility and possibility of wrapping ureter by a pedicled gastrocolic omentum flap combined with an artificial ureter external scaffold to prevent stoma stenosis in rabbit after ureterocutaneostomy.
methodsForty male New Zealand rabbits were involved in this study. For application of ureterocutaneostomy, the right ureter was wrapped by a pedicled gastrocolic omentum flap and combined with application of an artificial external scaffold, which served as experimental side. Traditional ureterocutaneostomy was applied in left ureter (control side). All rabbits were killed after 1 month, and the kidney, ureter and abdominal segment ureter were collected to study the morphological and pathological changes by using HE staining, Masson staining, immunohistochemistry staining and microvessel density (MVD) study.
resultsHE staining showed that renal medullary tubular dilatation, large number of collagen deposition, renal glomerular and renal tubular atrophy. Glomerular vascular leaves and interstitial fibrosis were detected in the kidney of control side. However, these abnormities in the kidney of experimental side were significantly alleviated compared to control side. The hydronephrosis and ureterectasia in the experimental side were dramatically attenuated compared to control side. Fibrosis in ureter around stoma and stoma stenosis were prevented by wrapping ureter by a pedicled gastrocolic omentum flap combined with an artificial external scaffold.
conclusionIn this study, we have demonstrated that wrapping ureter by a pedicled gastrocolic omentum flap combined with an artificial external scaffold is capable of preventing stoma stenosis in rabbit after ureterocutaneostomy, which provided a new method and theoretical basis for clinical application in the future.
