Haplotypes of RHO polymorphisms and susceptibility to age-related macular degeneration.

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
objectiveTo investigate whether haplotypes of rhodopsin (RHO) polymorphisms including rs7984, rs2855552, rs2855557 and rs2410 were associated with age-related macular degeneration (AMD) risk in Chinese Han population.
methodsGenotypes of rs7984, rs2855552, rs2855557 and rs2410 were detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 186 cases and 196 healthy controls. Then, the haplotypes were established with Haploview 4.2 software. And the effects of clinical charactersitics on the frequency of GTTG haplotype were also analyzed. Odds ratios (ORs) with 95% confidence interval (95% CI) were utilized to assess the relationship of haplotypes and genotypes of RHO polymorphisms with susceptibility to AMD.
resultsGenotype distribution of all polymorphisms in control group were all in agreement with Hardy-Weinberg equilibrium (HWE) (P>0.05). In the analysis, we found that mutant alleles of rs7984 and rs2855557 were both associated with increased risk of AMD. For genotype analysis, rs7984 AA and rs2855557AA, rs2410GG genotypes all could increase the risk for AMD (OR=1.905, 95% CI=1.143-3.174; OR=2.226, 95% CI=1.261-3.932; OR=2.073, 95% CI=1.105-3.888). However, rs2855552 showed no effects on the onset of AMD. Compared with GTTA, the haplotypes of GGTG, ATAA and GTTG were all related with AMD susceptibility. Further analysis suggested that age, hypertension and hyperlipidemia history play important roles in the frequency alteration of GTTG haplotype.
conclusionRHO polymorphisms (rs7984, rs2855557 and rs2410) and haplotypes may confer remarkable susceptibility to AMD. Further investigation showed that gene and environmental factors may work together in the pathogenesis of AMD.
