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

backgroundSo far, the miRNAs involved in multidrug resistance of esophageal cancer have not been reported. AIMS AND

methodsHere we have firstly investigated the roles of miR-27a in multidrug resistance of esophageal squamous cell carcinoma using MTT assay, flow cytometry assay, and reporter gene assay, etc.

resultsDown-regulation of miR-27a could confer sensitivity of both P-glycoprotein-related and P-glycoprotein-non-related drugs on esophageal cancer cells, and might promote ADR-induced apoptosis, accompanied by increased accumulation and decreased releasing amount of ADR. Down-regulation of miR-27a could significantly decrease the expression of P-glycoprotein, Bcl-2, and the transcription of the multidrug resistance gene 1, but up-regulate the expression of Bax.

conclusionsMiR-27a might play important roles in multidrug resistance of esophageal cancer. The further study of the biological functions of miR-27a might be helpful for developing possible strategies to treat esophageal cancer.
