Prognostic Role of microRNA-21 Expression in Brain Tumors: a Meta-analysis.

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
Many studies have shown that microRNAs have important roles in the development and progression of various cancers. Recent studies also showed that microRNA-21 expression may be associated with the prognosis of patients with several common cancers. However, there was still lack of evidence for the prognostic role of microRNA-21 expression in brain tumors. We performed a systemic review and meta-analysis of published and unpublished studies to assess the prognostic role of microRNA-21 expression in patients with brain tumors. PubMed, Embase, and Google Scholar databases were searched for eligible studies with data assessing the prognostic role of microRNA-21 expression in brain tumors. Pooled hazard ratios (HRs) of microRNA-21 expression for overall survival and 95% confidence intervals (CI) were calculated. Six studies from five publications were finally included into the meta-analysis. Those six studies included a total of 747 patients with brain tumors and 654 patients with gliomas. For overall survival, the pooled HR of higher microRNA-21 expression in patients with brain tumors was 1.82 (95% CI 1.29-2.58, P = 0.001). In patients with gliomas, the HR for overall survival of higher microRNA-21 expression was 1.83 (95% CI 1.09-3.09, P = 0.023). Sensitivity analysis by omitting one study by turns also showed there was no obvious influence of individual study on the pooled HRs. There was no obvious risk of publication bias in the meta-analysis. The present meta-analysis suggests that microRNA-21 is associated with the prognosis of patients with brain tumors, and high expression of microRNA-21 can predict poor prognosis in patients with brain tumors.
