Susceptibility to male infertility: replication study in Japanese men looking for an association with four GWAS-derived loci identified in European men.

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
purposeA previous genome-wide association study in European men identified four single nucleotide polymorphism (SNP) loci associated with male infertility. Our aim was to replicate, if possible, the association of these SNPs with Japanese male infertility.
methodsWe genotyped four SNPs (rs5911500, rs10246939, rs2059807, and rs11204546) in 517 Japanese patients with male infertility and 369 fertile controls using SNP-specific real-time polymerase chain reaction TaqMan assays. Subsequently, we divided patients with male infertility into azoospermia (n = 417) and oligospermia subgroups (n = 70).
resultsThe four SNPs previously identified in European men showed no significant association with collective male infertility in our Japanese cohort. However, allele frequency analysis did indicate a significantly higher frequency of the rs11204546 C allele of the OR2W3 gene in the oligospermia subset of infertility patients compared with controls (p = 0.0037; odds ratio = 1.74; 95 % confidence interval, 1.21-2.53).
conclusionsAlthough this study was somewhat limited by overall sample size, the OR2W3 gene polymorphism rs11204546 was significantly associated with oligospermia in Japanese men, suggesting that OR2W3 might be involved in genetic susceptibility to Japanese male infertility as well as in European males.
