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

The present study aimed to investigate the effect of treatment with epigallocatechin-3-gallate (EGCG) on the human esophageal cancer cell line ECa109 and elucidate the associated underlying mechanisms. ECa109 cells were cultured and treated with increasing concentrations of EGCG for various durations. Cell viability was evaluated using the MTT assay and apoptosis was detected using flow cytometry. The methylation status of the cyclin-dependent kinase inhibitor 2A (p16) gene was analyzed using the methylation-specific polymerase chain reaction (PCR). p16 mRNA and protein expression was measured using reverse transcription-quantitative PCR and western blot analysis, respectively. The results of the present study demonstrated that, following treatment with EGCG, ECa109 cell viability was significantly decreased, while the rate of apoptosis was significantly increased (P<0.01), in a dose- and time-dependent manner. Following treatment of ECa109 cells with EGCG, p16 gene demethylation, and its mRNA and protein expression, were significantly increased compared with the untreated cells (P<0.01). EGCG may induce ECa109 cell apoptosis and inhibit cell growth through p16 gene demethylation, which restores its expression.
