Effect of lymph node resection on prognosis of resectable intrahepatic cholangiocarcinoma: A systematic review and meta-analysis.
Review in Frontiers in oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 4 of them syntheses that pooled 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.
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
Background: The purpose of this meta-analysis was to evaluate the efficacy of lymph node dissection in patients with intrahepatic cholangiocarcinoma (ICC). Methods: The literature from January 2009 to December 2021 was searched to determine the comparative study of lymph node dissection and non-lymph node dissection in patients with ICC. Results: Seventeen studies were included in the analysis. There were no significant differences in 1-, 3-, and 5-year overall survival (OR = 0.80, p = 0.10; OR = 0.93, p = 0.71; OR = 0.80, p = 0.21) and 1-, 3-, and 5-year disease-free survival (OR = 0.89, p = 0.73; OR = 0.92, p = 0.81; OR = 0.85, p = 0.62). Conclusions: Lymph node dissection does not seem to have a positive effect on the overall survival and disease-free survival.
