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
Introduction: Allium metal ureteral stents have become an increasingly popular endoscopic treatment option for ureteral strictures. This study aimed to present the outcomes of Allium ureteral stents in the treatment of refractory ureteral strictures of different origin at a single center. Material and methods: The objective of our study is to present the retrospective analysis of patients treated with an Allium ureteral stent in our department and to evaluate its effectiveness. The success rate of treatment, postoperative resolution in hydronephrosis, symptom and complication rates were evaluated during the follow-up period. The study group consisted of 18 patients with unilateral or bilateral hydronephrosis due to the ureteral stricture of different etiologies. Results: The total percentage of regression of hydronephrosis was observed in 77.78% of cases. The median follow-up period was 575 days. The main causes of hydronephrosis were urolithiasis and its previous treatment, as well as neoplastic diseases of the abdomen and pelvis. Conclusions: The study found that the use of Allium ureteral stents can be an effective and helpful option in the treatment of ureteral strictures, especially in cases where primary treatment options are not suitable.
