Stent insertion for hilar cholangiocarcinoma: a meta-analysis of comparison between unilateral and bilateral stenting.
Review in Przeglad gastroenterologiczny, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis 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.
Who cites it

Abstract
introductionMetal stenting can be used as a primary treatment option for alleviating malignant hilar biliary obstruction (MHBO) symptoms. Although many studies have focused on the topic of unilateral or bilateral stenting for MHBO, there is a clear need for a study comparing these two stenting types in patients with a single type of cancer.
aimThis meta-analysis was conducted to evaluate the relative clinical efficacy of unilateral and bilateral metal stent insertion for hilar cholangiocarcinoma (HCCA). MATERIAL AND
methodsThe PubMed, Embase, and Cochrane Library databases were searched to identify all relevant studies. This meta-analysis was conducted using RevMan v5.3.
resultsWe initially identified 154 studies, seven of which were included in the final meta-analysis. These studies contained 524 HCCA patients treated by either unilateral (
conclusionsCompared to bilateral metal stenting, unilateral metal stenting could provide a similar clinical efficacy for patients with HCCA with a lower complication rate.
