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
introductionGastric antral vascular ectasia (GAVE) is a condition characterized by clusters of dilated capillaries in the gastric antrum, leading to gastrointestinal bleeding. Although massive hemorrhage is rare, some cases present with recurrent minor bleeding, which can make endoscopic hemostasis challenging. Here, we report a case of GAVE that was refractory to argon plasma coagulation (APC) and required surgical intervention. CASE PRESENTATION: A 74-year-old man with end-stage renal disease who was on hemodialysis was referred to our hospital for evaluation of refractory anemia. Upper gastrointestinal endoscopy revealed the characteristic "watermelon stomach" appearance, with radially and longitudinally distributed dilated capillaries in the gastric antrum, leading to a diagnosis of GAVE. Despite undergoing APC 4 times, his anemia persisted. Given the refractory nature of the condition, surgical intervention was considered. To preserve the stomach, we initially performed laparoscopic gastric antral devascularization to reduce the blood flow to the affected area. Intraoperatively, dilated marginal vessels were observed along the greater curvature of the gastric antrum. The marginal artery was ligated along the greater curvature from the watershed area to the pylorus and pyloric ring. Indocyanine green (ICG) fluorescence imaging revealed delayed enhancement in the marginal artery resection area, indicating reduced perfusion. However, after a 2-month postoperative observation period, no improvement in the anemia was observed, and follow-up endoscopy revealed no significant changes in the gastric antral lesions. Consequently, a laparoscopic distal gastrectomy was performed. Following the procedure, the anemia stabilized, and the postoperative course was uneventful.
conclusionsGastric antral devascularization was ineffective for the treatment of GAVE, even when combined with ICG blood flow assessment. For refractory GAVE unresponsive to endoscopic therapy, a distal gastrectomy appears to be the most effective treatment.
