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

purposeThe incidence of LNM and survival outcomes following routine lymph node dissection (LND) in patients undergoing resection of hepatocellular carcinoma (HCC), intrahepatic- (ICC) and perihilar cholangiocarcinoma (PCC) has not been well-defined. This systematic review and meta-analysis analyzes the incidence of LNM and survival outcomes following routine LND independently of pre-or intraoperative suspicion of LNM following resection of HCC, ICC, and PCC.

methodsThe PubMed database was searched from database inception until March, 2025. Random-effects meta-analysis of the incidence of LNM and hazard ratios (HRs) of overall survival (OS) were conducted for each malignancy.

resultsForty studies were included. Routine LND was performed in 5 872 patients. The pooled incidence of LNM following routine LND was 5% among 601 HCC patients, 37% among 2 565 ICC patients, and 39% among 2 706 PCC patients. Presence of LNM was associated with worse OS in ICC (HR: 2.46, 95% CI 1.66-3.65) and PCC (HR: 2.01, 95% CI 1.74-2.33) patients.

conclusionRoutine LND should be performed during resection of ICC and PCC due to the high incidence of LNM and improved survival outcomes, but not during resection of HCC. The presence of LNM gives inferior survival outcomes in ICC and PCC patients.
