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

purposeVascular resection (VR) is extended surgery to attain a negative radial margin (RM) for distal cholangiocarcinoma (DCC). The present study explored the significance of VR for DCC, focusing on VR, RM, and findings suggestive of vascular invasion on multidetector-row computed tomography (MDCT).

methodsPatients with DCC who underwent resection between 2002 and 2019 were reviewed.

resultsAmong 230 patients, 25 received VR. The overall survival (OS) in the VR group was significantly worse than in the non-VR group (16.7% vs. 50.7% at 5 years, P < 0.001). Patients who underwent VR with a negative RM failed to show a better OS than those who did not undergo VR with a positive RM (19.7% vs. 35.7% at 5 years, P = 0.178). Of the 30 patients who were suspected of having vascular invasion on MDCT, 11 did not receive VR because the vessels were freed from the tumor; these patients had a significantly better OS (57.9% at 5 years) than those who underwent VR.

conclusionsVR for DCC was associated with a poor prognosis, even if a negative RM was obtained. VR is not necessary for DCC when the vessels are detachable from the tumor.
