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

contextGenetically determined heightened androgen sensitivity may influence the phenotype of polycystic ovary syndrome (PCOS). To date, studies of the androgen receptor exon 1 polymorphic CAG repeat have produced conflicting results in PCOS.

objectiveWe tested the hypothesis that a lower number of CAG repeats is associated with increased odds of PCOS. We also compared X-chromosome inactivation between cases and controls.

designWomen with and without PCOS were genotyped for the CAG repeat and assessed for X-chromosome methylation. Association analyses were performed.

settingSubjects were recruited from the reproductive endocrinology clinic at the University of Alabama at Birmingham; controls were recruited from the surrounding community. Genotyping took place at Cedars-Sinai Medical Center in Los Angeles.

participantsParticipants included 330 women with PCOS and 289 controls (77% white, 23% black). MAIN MEASUREMENTS: Androgen receptor genotype, X-chromosome methylation, and phenotyping for PCOS were measured.

resultsA smaller biallelic mean of CAG repeats was associated with increased odds of PCOS. X-chromosome inactivation was not different comparing cases with controls; however, in the subset with nonrandom inactivation, the chromosome bearing the shorter CAG allele was preferentially active in PCOS women.

conclusionsAssociation of shorter CAG repeats with PCOS is consistent with in vitro functional studies demonstrating higher activity of androgen receptors expressed from alleles with fewer CAG repeats, suggesting inherited alteration in androgen sensitivity may contribute to PCOS. In some women, such heightened sensitivity may also result from preferential expression of androgen receptors with shorter alleles. Thus, genetic and epigenetic changes may be involved in the pathogenesis of PCOS.
