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 and Aims: Surgical reversal of Roux-en-Y gastric bypass (RYGB) is associated with high morbidity but may be necessary in patients with malnutrition. In recent years, endoscopic gastrogastric (GG) fistulas created via lumen-apposing metal stents (LAMSs) have offered patients a less-invasive alternative, but they are associated with adverse events if left in situ for long periods of time. We describe the use of a double-LAMS septotomy technique with septotomy to achieve permanent and durable partial RYGB reversal. Methods: A 39-year-old man with severe malnutrition (body mass index [BMI] 18.4 kg/m Results: There were no intraprocedural or postprocedural adverse events. The patient was discharged on a liquid diet and transitioned to a regular solid diet. He maintained weight gain (BMI 28 kg/m Conclusions: EUS-guided double-LAMS septotomy is safe, minimally invasive, and durable for partial permanent reversal of RYGB in high-risk patients.
