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

purposeDNA methylation is one of the most extensively studied mechanisms within epigenetics, and it is suggested that diet-induced changes in methylation status could be involved in energy metabolism regulation. Conjugated linoleic acid (CLA) and calcium supplementation counteract body weight gain, particularly under a high-fat (HF) diet, in adult mice. The aim was to determine whether the modulation of DNA methylation pattern in target genes and tissues could be an underlying mechanism of action.

methodsMice (C57BL/6J) were divided into five groups according to diet and treatment: normal fat as the control group (12 % kJ content as fat), HF group (43 % kJ content as fat), HF + CLA (6 mg CLA/day), HF + calcium (12 g/kg of calcium) and HF with both compounds. Gene expression and methylation degree of CpG sites in promoter sequences of genes involved in fatty acid metabolism, including adiponectin (Adipoq), stearoyl-CoA desaturase (Scd1) and fatty acid synthase (Fasn), were determined by bisulphite sequencing in liver and epididymal white adipose tissue.

resultsResults showed that the methylation profile of promoters was significantly altered by dietary supplementation in a gene- and tissue-specific manner, whereas only slight changes were observed in the HF group. Furthermore, changes in specific CpG sites were also associated with an overall healthier metabolic profile, in particular for calcium-receiving groups.

conclusionsBoth CLA and calcium were able to modify the methylation pattern of genes involved in energy balance in adulthood, which opens a novel area for increasing efficiency in body weight management strategies.
