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

The adult male muskrat has a pair of scented glands, which show clear seasonal changes in their developmental status between the secretion season and non-secretion season. During the secretion season, the scented glands are much larger than in the non-secretion season, with the metabolism of glandular cells increasing and a large amount of musk being produced. In this work, the blood, musk, and scented gland tissue were collected from three healthy adult male muskrats during secretion season (September). And the blood and scented gland tissue from another three healthy adult male muskrats during the non-secretion season (November) were also sampled. The saccharides from blood and musk were detected by liquid chromatography-mass spectrometry (LC-MS), indicating the saccharides are concentrated in the scented glands during the secretion season. What is more, transcriptome analysis was employed to investigate the expression patterns of saccharides' pathways, suggesting some saccharides' metabolism-related genes undergo significant seasonal changes. Above all, scented gland saccharides' metabolism displays seasonal differences, and the enhancement in saccharides' metabolic activity during the secretion phase maintains glandular proliferation and secretion function.
