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

Y chromosome (ChrY), the male-specific sex chromosome, has been considered as a genetic wasteland. Aging-related mosaic loss of ChrY (LOY) has been known for more than half a century, but it was constantly considered as a neutral karyotype related to normal aging. These views have been challenged with genome-wide association studies identifying mosaic LOY in human somatic cells is the most commonly acquired mutation in male's genome and is associated with a wide spectrum of human diseases including cancer, Alzheimer's disease, and cardiovascular disease. These previously undescribed clinical significances deeply modify our perception on ChrY and open up a range of new questions. Here, we review the latest advances in our knowledge of the biological origins and clinical consequences of mosaic LOY. We highlight the association of mosaic LOY to pathogenic conditions and evaluate the cause-and-consequence relationships between mosaic LOY and pathogenesis. The known risk factors of mosaic LOY including age, genetic variants, ChrY structural aberrations and environmental stressors are discussed. In light of evidence from pioneering and more recent studies, we propose the micronucleation hypothesis and centromere-dysfunction and telomere-attrition models to explain how mosaic LOY occurs and why ChrY is prone to lose. We believe it is importantly and timely to extend mosaic LOY research from epidemiological associations to mechanistic studies. In this regard, we outline important gaps and assess several future directions from a biological and clinical perspective. An improved understanding of mosaic LOY will open new pathways to modify and increase healthy aging in males.
