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

purposePrevious studies identified follicle-stimulating hormone receptor (FSHR) and luteinizing hormone/choriogonadotropin receptor (LHCGR) genes as polycystic ovary syndrome (PCOS) susceptibility loci, which was dependent on the racial/ethnic background of studied population. We investigated the association of genetic variants in FSHR and LHCGR with PCOS in Bahraini Arab women.

methodsA retrospective case-control study, involving 203 women with PCOS, and 211 age- and ethnically-matched control women. FSHR and LHCGR genotyping was done by allelic exclusion method (real-time PCR).

resultsSignificantly lower frequencies of heterozygous LHCGR rs7371084 and FSHR rs11692782 genotype carriers were seen between women with PCOS vs. controls, and increased frequency of heterozygous homozygous LHCGR rs4953616 genotype carriers were detected between women with PCOS compared to control women. Limited linkage disequilibrium was noted among LHCGR and FSHR SNPs, and 2 blocks were constructed: the first (Block 1) spanning 61 kb contained the six tested LHCGR SNPs, and the second (Block 2) spanning 298 kb contained four of the five tested FSHR SNPs. Higher frequency of LHCGR GTCAAG haplotype was seen in women with PCOS compared to controls; the frequencies of the remaining LHCGR haplotypes, and all FSHR haplotypes were similar between cases and controls.

conclusionThis is the first study to confirm the association of novel LHCGR (rs7371084, rs4953616) and FSHR (rs11692782) SNPs with PCOS. The differential association of LHCGR and FSHR variants with PCOS confirms the racial/ethnic contribution to their association with PCOS.
