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

In March 2021, the Japanese TNM Classification for Cancer of the Biliary Tract (JCCB) was revised. This study aimed to validate the 7th edition of JCCB based on long-term outcomes after resection for distal cholangiocarcinoma (DCC). We retrospectively reviewed 107 patients with resected DCC without distant metastasis between 2007 and 2019. Survival curves according to TNM factors were compared between the 6th and 7th editions. The 5-year overall survival (OS) and recurrence-free survival rate (RFS) were 43.4% and 35.5%, respectively. Significant differences in OS were observed between T categories in the 7th edition (T1
