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

BACKGROUND/

aimDuring metastatic disease development, the cancer-immune system crosstalk induces epigenetic modifications to immune cells, impairing their functions. Recently, Alu elements methylation changes were widely studied in terms of early cancer detection. This study aimed to demonstrate in vitro Alu element methylation changes in peripheral immune cells in a metastatic setting and examine their prognostic values in metastatic breast cancer. MATERIALS AND

methodsSera from sixteen metastatic cancer patients and sixteen healthy participants were obtained and used to culture normal peripheral immune cells. After 48 h of incubation, the percentage and pattern of Alu element methylation were examined for clinical relevance.

resultsWe found that the Alu element hypomethylation was affected by age in the cancer group. Intriguingly, a decrease in Alu element methylation was found in patients with early progressive disease. Moreover, an increase in unmethylated cytosine (mCuC) loci was related to the poorer prognosis group. Accordingly, the decrease in Alu element methylation and the increase in mCuC loci pattern in peripheral immune cells correlated with poorer prognosis and early progression in metastatic breast cancer.

conclusionAlu element hypomethylation in immune cells and their increased mCuC foci were related to the early progression of breast cancer. These warrant the use of Alu element methylation changes for diagnostic and therapeutic purposes in breast cancer.
