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 and importancePancreatic body cancers encasing the celiac axis present a formidable surgical challenge, historically deemed inoperable due to the risk of gastric and hepatic ischemia. The modified Appleby procedure, involving distal pancreatectomy with en bloc celiac axis resection, offers curative potential in carefully selected cases. We report a rare and uncharted vascular variant that enabled safe execution of this procedure with preservation of organ perfusion. CASE PRESENTATION: A 58-year-old male presented with epigastric discomfort, weight loss, and a 4-cm pancreatic body tumor encasing the celiac axis. Contrast-enhanced CT and 3D angiography revealed a replaced left hepatic artery (LHA) originating from the left gastric artery (LGA), with strong collateral flow from the superior mesenteric artery (SMA). During surgery, the gastroepiploic arcade was sacrificed. However, intraoperative Doppler confirmed a novel collateral circuit-SMA → GDA → PHA → segment 4 → segments 2/3 → LGA via replaced LHA-preserving both hepatic and gastric perfusion. The procedure was completed without complications. Postoperative recovery was uneventful apart from transient delayed gastric emptying. Histology confirmed a moderately differentiated pancreatic ductal adenocarcinoma with R0 resection. CLINICAL DISCUSSION: This is the first reported case demonstrating effective retrograde gastric perfusion via a replaced LHA following celiac axis resection. It highlights how variant anatomy, if preserved, can be safely leveraged to extend resectability criteria in pancreatic cancer.
conclusionMeticulous vascular mapping and intraoperative perfusion assessment can unlock curative surgical options in anatomically complex pancreatic tumors.
