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
Glioma is a prevalent primary brain tumor. Temozolomide (TMZ) has been used to treat glioma. However, the resistance of TMZ to glioma poses heavy burden to glioma treatment. In this study, the effects of glioma resistance to TMZ and underlying mechanism were revealed. The expression levels of circ-VPS18, microRNA-370 (miR-370) and runt-related transcription factor 1 (RUNX1) were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The protein expression of RUNX1, multidrug resistance-associated protein 1 (MRP1), and multi-drug resistance gene-1 (MDR1) was determined by western blot. The functional effects of circ-VPS18 knockdown on TMZ sensitivity and glioma progression were revealed by cell counting kit-8 proliferation (CCK-8), flow cytometry, and transwell assays. The impacts of circ-VPS18 deletion on TMZ sensitivity in vivo were illustrated by in vivo tumor formation assay. The binding relationship between miR-370 and circ-VPS18 or RUNX1 was predicted by starBase v2.0 online database and identified by dual-luciferase reporter assay. Circ-VPS18 expression and the mRNA and protein levels of RUNX1 were dramatically upregulated, and miR-370 expression was significantly downregulated in glioma cells, TMZ-resistant glioma tissues, or tissue compared with control groups. Functionally, circ-VPS18 knockdown improved TMZ sensitivity, induced cell apoptosis, whereas repressed cell viability, migration and invasion in U251/TR and LN229/TR cells, which was reversed by miR-370 inhibitor. Additionally, RUNX1 overexpression hindered the effects of miR-370 on TMZ sensitivity and glioma progression. Circ-VPS18 knockdown enhanced TMZ sensitivity in vivo. Mechanistically, circ-VPS18 functioned as a sponge of miR-370 and miR-370 targeted RUNX1. Circ-VPS18 knockdown improved TMZ sensitivity and repressed glioma progression by sponging miR-370 to downregulate RUNX1 expression, which provided a new insight in further studying glioma resistance to TMZ.
