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

backgroundSurgical treatment is currently the only way to achieve the clinical cure for Klatskin tumor. However, whether combined vascular resection should be combined during surgeries is still controversial. The aim of this article was to analyze the effect of portal vein resection (PVR) and hepatic artery resection (HAR) on the long-term survival after surgery for Klatskin tumor.

methodsArticles about Klatskin tumor with PVR and HAR, which were published from 2000 to 2020, were searched using PubMed, Embase, and EBSCO. HR with a 95% CI of overall survival, recurrence-free survival, disease-free survival, 3- and 5-year survival rate, and median survival time were reported to evaluate prognosis.

resultsA total of 17 articles were included. The total case number of these studies was 3150 (685 in the PVR group, 345 in the HAR group, and 2120 in the control group). Survival analyses showed that both vascular resection types were poor prognostic factors (PVR: HR = 1.50, 95% CI = 1.24-1.81, P < 0.001; HAR: HR = 1.68, 95% CI = 1.26-2.24, P < 0.001; the pooled effect size of the two groups: HR = 1.55, 95% CI = 1.32-1.82, P < 0.001). In general, the analyses of 3- and 5-year survival and median survival time showed that both vascular resection types tended to be poor prognostic factors, but most of recent researches showed that the PVR did not lead to a poor prognosis.

conclusionPVR should be used when necessary to achieve R0 resection of Klatskin tumor and improve the long-term survival of patients. Whether HAR should be performed or not is still need to be evaluated.
