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

objectivesThe main aim of this work was to analyse the potential tumour growth inhibition effects of (-)-epicatechin (EC). Triple-negative breast cancer (TNBC) is an invasive form of cancer characterized by the absence of progesterone receptor, estrogen receptor and human epidermal growth factor receptor 2. Doxorubicin (DOX) is widely used for its anti-tumour activity. EC belongs to the flavanol subfamily and is a candidate molecule for the adjuvant treatment of cancer due to its antiproliferative activities.

methodsEvaluation of EC effects and pathways involved in a model of TNBC. KEY

findingsEC inhibited tumour growth as efficiently as DOX (inhibition rates of 74% and 79% for EC and DOX, respectively). The evaluation of adenosine monophosphate-activated protein kinase (AMPK) and Akt phosphorylation and mTOR expression indicates that EC modulates these pathways, resulting in the inhibition of cell proliferation. Additionally, we found an increase in the survival of EC-treated animals compared with control-treated animals. This effect was similar to the effects induced by DOX (survival rates of 44% and 30% for EC and DOX, respectively).

conclusionEC has antiproliferative properties and increases survival in a model of TNBC. These effects may occur through the modulation of deregulated AMPK and Akt/mTOR signalling pathways.
