Sex-stratified genome-wide meta-analysis identifies novel loci for cognitive decline in older adults.

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.
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
introductionMany complex traits and diseases show sex-specific biases in clinical presentation and prevalence.
methodsTo understand sex-specific genetic architecture of cognitive decline across five cognitive domains (attention, memory, executive function, language, and visuospatial function) and global cognitive function, we performed sex-stratified genome-wide meta-analysis in 3021 older adults aged ≥ 65 years (female = 1545, male = 1476) from three prospective cohorts. Gene-based and gene-set enrichment analyses were conducted for each cognitive trait.
resultsWe identified a novel genome-wide significant (GWS) intergenic locus for decline of memory in males near RPS23P3 on chromosome 4 (rs6851574: minor allele frequency [MAF] = 0.39, P DISCUSSION: Sex-aware genetic studies can help in the identification of novel genetic loci and enhance sex-specific understanding of cognitive decline. HIGHLIGHTS: Our genome-wide meta-analysis of single variants identified two new genetic associations, one in males and one in females. The novel male association was observed with the decline of memory in the intergenic region near the RPS23P3 gene on chromosome 4. This intergenic region has previously been implicated in several brain and cognition related traits, including anatomical brain aging, brain shape, and educational attainment. The novel female-specific association was observed with decline in executive function on chromosome 12 near the NDUFA12 gene, which is involved in oxidative phosphorylation. Sex-stratified analyses offer sex-specific understanding of biological pathways involved in cognitive aging.
