1 · What the graph read from it

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.

2 · The registry

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

Distal pancreatectomy with celiac axis resection (DP-CAR) is performed for locally advanced pancreatic body cancers involving the common hepatic artery (CHA) and/or celiac axis (CA). This procedure becomes especially intractable in cases of portal vein (PV) invasion due to poor mobility around both the CA and PV. However, no previous reports have described the surgical strategies for such difficult situations. To overcome the difficulty of CA and PV invasion, we devised a novel procedure called "pre-resection portal vein reconstruction." In this procedure, PV reconstruction using an inferior mesenteric vein patch graft is implemented after division of the CHA and pancreatic neck. The greatest advantage of this procedure is improved mobility around the pancreatic body after PV reconstruction, thereby enabling a subsequent sequential approach around the superior mesenteric artery, abdominal aorta, and CA root. "Pre-resection portal vein reconstruction" is an option for locally advanced pancreatic body cancers with both CA and PV invasion.
