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

backgroundAlthough lymph node metastasis is a known factor predictive of a poor prognosis after radical surgery for intrahepatic cholangiocarcinoma (ICC), few studies have investigated lymph node dissection (LND) areas for accurate staging. The aim of this study was to identify the optimal LND level for ICC considering lymphatic flow.

methodsClinical characteristics and pathologic nodal status (presence of metastasis) for 163 patients were reviewed according to tumor location. In the node-positive (N1) group, the distribution of metastatic nodes was described. The coverage of metastatic nodes according to dissection level was assessed, and the minimum dissection level for accurate ICC staging was estimated accordingly. For validation, the node-negative (N0) group was divided into two subgroups according to the estimated dissection level, and survival outcomes were compared.

resultsIn the N1 group, expanding dissection to stations no. 12 and 8 covered 82.0% (n = 50) of metastatic cases regardless of tumor location. In survival analysis of N0 group, patients who underwent LND covering stations no. 8+12 showed better disease-free survival (DFS) and overall survival (OS), although the differences were not statistically significant (DFS: covering no. 12+8 vs. not covering no. 12+8, 109.0 months [24.2-193.8] vs. 33.0 months [10.3-55.7], p = 0.078; OS: covering no. 12+8 vs. not covering no. 12+8, 180.0 months [21.6-338.4] vs. 73.0 months [42.8-103.2], p = 0.080).

conclusionLND including at least stations no. 12 (hepatoduodenal ligament) and 8 (common hepatic artery), regardless of tumor location, is recommended for accurate staging in ICC patients.
