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

S-Adenosylmethionine (SAM) is the primary methyl donor for numerous cellular methylation reactions. Its central role in methylation and involvement with many pathways link its availability to the regulation of cellular processes, the dysregulation of which can contribute to disease states, such as cancer or neurodegeneration. Emerging evidence indicates that intracellular SAM levels are maintained within an optimal range by a variety of homeostatic mechanisms. This suggests that the need to maintain SAM homeostasis represents a significant evolutionary pressure across all kingdoms of life. Here, we review how SAM controls cellular functions at the molecular level and discuss strategies to maintain SAM homeostasis. We propose that SAM exerts a broad and underappreciated influence in cellular regulation that remains to be fully elucidated.
