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

backgroundAccumulated studies have revealed that vascular endothelial growth factor (VEGF) plays an essential role in the progression of glioma, but the prognostic significance of VEGF expression for patients with glioma remains unknown. METHOD AND MATERIAL: A literature search of public databases (PubMed, ISI Web of Science, Science Direct, Cochrane Central Register of Controlled Trials, Wiley Online Library, China National Knowledge Infrastructure, China Biology Medicine disc, Chongqing VIP and Wan Fang Data) was conducted. A meta-analysis was performed to evaluate the association between the overexpression of VEGF and the survival for the glioma patients. Subsequently we evaluated the impact of VEGF expression on the pathological grade of glioma.

resultsA total of 32 articles with 2307 cases contributed to this analysis, of which 31 reported overall survival (OS) and 5 reported progression-free survival (PFS). In this meta-analysis, VEGF overexpression significantly identified the unfavorable outcome on OS (HR = 1.647, 95% CI: 1.324~2.048, P < 0.001, Z = 4.48) but not on PFS (HR = 1.021, 95% CI: 0.974~1.070, P = 0.393). Subgroup analyses also revealed that high level of VEGF was associated with the poor OS for the patients with glioma according to region, case number, specimen type, method to detect VEGF and statistical method. Furthermore, the significant correlation was achieved between VEGF expression and the pathological grade of glioma (r = 0.307, P < 0.001).

conclusionThis study suggests that VEGF expression is significantly correlated with the glioma progression and may be a valuable prognostic factor on OS for the glioma patients.
