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
Gastrosplenic fistula is a rare complication, most often secondary to gastric or splenic lymphoma. Severe gastrosplenic fistula can cause life-threatening upper gastrointestinal bleeding, making early diagnosis and intervention critical for a favorable prognosis. Currently, surgical intervention remains the primary treatment; however, outcomes are often suboptimal. In this paper, we present a case involving ultrasound-guided interventional diagnosis and treatment of gastrosplenic fistula caused by diffuse large B-cell lymphoma. An 18-year-old male initially presented with gastric distension and epigastric pain and was diagnosed with gastric non-Hodgkin lymphoma (diffuse large B-cell lymphoma) at an outside hospital before being referred to our institution for further management. Contrast-enhanced CT revealed an abnormal density lesion between the gastric fundus and spleen, suggestive of gastric perforation accompanied by adjacent exudation and localized abscess formation. A multidisciplinary team evaluation identified markedly elevated inflammatory markers and poor overall condition, rendering the patient unsuitable for immediate surgery. Subsequent B-mode ultrasound and contrast-enhanced ultrasound (CEUS) precisely delineated the fistula location and extent of the abscess, enabling determination of a safe puncture path. Ultrasound-guided percutaneous catheter drainage of the gastrosplenic fistula was then successfully performed. Post-procedural intracavitary contrast injection confirmed correct catheter tip placement distal to the fistula. Follow-up CT imaging 20 days after drainage showed a significant reduction in the encapsulated fluid and gas collection at the fistula site. After one month of clinical improvement, the patient underwent total gastrectomy with resection of the pancreatic body-tail and spleen. He was subsequently discharged and continued maintenance chemotherapy for non-Hodgkin lymphoma. At 13 months postoperatively, the patient remains clinically stable with normal vital signs.
