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

objectiveTo systematically evaluate the relationship between vascular endothelial growth factor (VEGF) and prognosis of intrahepatic cholangiocarcinoma by meta-analysis.

methodsWe systematically searched relevant studies in the databases of PubMed, Embase, Cochrane Library, CNKI, Wangfang, and Web of Science, with search dates limited to September 1, 2021. We extracted relevant data, including prognosis and clinicopathological features of patients with different expressions of VEGF in intrahepatic cholangiocarcinoma. The combined hazard ratio (HR), odds ratio (OR), and 95% confidence interval (CI) were calculated to evaluate the link strength between VEGF and prognosis of cholangiocarcinoma patients.

resultsA total of 7 eligible studies with 495 patients were included in this meta-analysis. The results showed that the high expression of VEGF was significantly related to poor overall survival (OS) (HR = 1.93, 95% CI 1.52-2.46, P < 0.05) in patients with intrahepatic cholangiocarcinoma. Moreover, high expression of VEGF in tumor tissues associated with lymph node metastasis (LNM) (OR = 6.79, 95% CI 3.93-11.73, P < 0.05) and advanced TNM stage (OR = 4.35, 95% CI 2.34-8.07, P < 0.05) in intrahepatic cholangiocarcinoma. Sensitivity analysis shows that the meta-analysis results are stable and reliable.

conclusionThe expression of VEGF is related to the OS of patients with intrahepatic cholangiocarcinoma, and the OS of patients with high expression of VEGF is shorter. VEGF may be a novel predictor of intrahepatic cholangiocarcinoma patients.
