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

Purpose: To evaluate the patterns of locoregional recurrence (LRR) in patients with perihilar extrahepatic cholangiocarcinoma (PEHC) treated with radical resection and to suggest the optimal target volume for elective nodal irradiation. Methods: Medical records of PEHC patients who underwent radical resection between January 2000 and September 2021 at five institutions were reviewed. Patients who were confirmed with LRR in the follow-up imaging study were included. The LRR sites were mapped onto the corresponding sites in template computed tomography images. The margin around the vascular structure was investigated to generate the clinical target volume (CTV) covering the common sites of regional recurrences. Results: A total of 87 LRRs in 46 patients were identified, 29 (33.3%) of which were local recurrences and 58 (66.7%) were regional recurrences. The most common site of local recurrence was the liver resection margin ( Conclusions: The LRR patterns in the resected PEHC were evaluated and specific guidelines for nodal CTV delineation were provided, which may help physicians delineating the target volume in postoperative radiotherapy for PEHC. These findings need further validation in a lager cohort.
