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
introductionMicroRNAs are regulatory non-coding RNAs, with their outstanding regulatory mechanism, that make them potential biomarker for disease detection and therapeutics. They play an important role in pathological state, such as cancer by acting as oncogenic microRNAs and tumor suppressor microRNAs. The expression of microRNA-206, microRNA-4477a, microRNA-4795-5p, microR-4796-3p, microRNA-451b, and microRNA-4311 has proven to be deregulated in different cancer studies. However, no comprehensive study has been reported yet regarding their role in glioma patients.
aimThe present study is designed to examine the expression profiling of microRNAs, such as microRNA-206, microRNA-4477a, microRNA-4795-5p, microR-4796-3p, microRNA-451b, and microRNA-4311 in glioma patients. Furthermore, the expression deregulation of selected microRNAs was correlated with oxidative stress and proliferation rate in glioma patients.
methodsFor this purpose, 153 glioma tissue samples and 200 brain tissues from epilepsy patients (taken as controls) were collected in the present study. Expression analysis of selected microRNAs was carried out on collected samples using real-time PCR (qPCR). Oxidative stress and proliferation rate were measured by estimation of 8OXOG level and Ki-67 using the ELISA and IHC.
resultsOur results showed significant deregulation of microRNA-206 (p < 0.0001), microRNA-4477a (p < 0.01), microRNA-4311 (p < 0.0001), microRNA-4795-5p (p < 0.0001), microRNA-4796-3p (p < 0.0001), and microRNA-451b (p < 0.0001) in glioma patients compared to controls. However, significant upregulation of 8OXOG level (p < 0.0001) and Ki-67 (p < 0.0001) was observed in glioma patients compared to controls. Kaplan-Meier analysis showed that deregulated expression of selected microRNAs was associated with significant decrease in survival of glioma patients.
conclusionsOur results demonstrated significant deregulation of selected microRNAs in glioma patients. This deregulated expression was found associated with significant increased risk of glioma and could be further developed as effective prognostic biomarker and therapeutic tool in said disease.
