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

Breast cancer is the most common cancer and the second leading cause of cancer-related mortality worldwide. The etiology of breast cancer is very diverse and ethanol (EtOH) consumption is a well-established risk factor for breast cancer in women. However, the mechanism by which EtOH exerts its carcinogenic activity in breast tissue remains unknown. CYP2E1 is known to metabolize ethanol and produce reactive oxygen species (ROS), including superoxide in epithelial cells. Therefore, in the present studies, we investigated whether there is an increase in ROS following overexpression of CYP2E1 in MCF-10A cells. We found that 30 and 100 mM EtOH increased ROS levels after 2 h treatment in CYP2E1 overexpressing cells. Based on these results and our previous studies with ROS-producing chemicals, we also examined epidermal growth factor receptor (EGFR) activation following exposure to ethanol. We found that there was an increase in phosphorylation of pY1086 EGFR after 18 h EtOH treatment in CYP2E1 overexpressing cells. These studies support a hypothesis that EtOH might increase human mammary cell activation, via an EGFR-dependent signaling mechanism associated with oxidative stress.
