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

Objective To investigate the effect and mechanism of action of metformin on proliferation of a human hypopharyngeal carcinoma cell line (FaDu). Methods FaDu cells were treated with metformin (25-125 mmol/l). Cell proliferation was evaluated via CCK-8 assay. Real-time quantitative reverse transcription-polymerase chain reaction was used to evaluate microRNA (miR)-21-5p and PDCD4 (programmed cell death 4) expression. PDCD4 protein was quantified by Western blot. Results Metformin significantly inhibited FaDu cell proliferation in a dose- (25-100 mmol/l) and time-dependent manner (12 h-36 h), significantly downregulated miR-21-5p, and upregulated PDCD4 mRNA and protein expression. Conclusions Metformin significantly inhibited FaDu cell proliferation , possibly via downregulation of miR-21-5p and upregulation of PDCD4.
