Genetic markers of lipid metabolism genes associated with low susceptibility to HCV infection.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Due to the relation between lipids and Hepatitis C virus (HCV) life-cycle, we aimed to explore the existence of single nucleotide polymorphisms (SNPs) associated with low susceptibility to HCV-infection within lipid metabolism genes. This was a case-control study in three phases: (I) allelic frequencies of 9 SNPs within 6 genes were compared in 404 HCV-infected patients and 801 population controls; (II) results were validated in 602 HCV-infected individuals and 1352 controls; (III) results were confirmed in 30 HCV-exposed uninfected (EU) individuals. In phase I, only the LDLRAP1-rs4075184-A allele was differentially distributed in patients and controls (358 of 808 alleles [44.3%] and 807 of 1602 alleles [50.3%], respectively) (p = 0.004). In phase II, the A allele frequency was 547 of 1204 alleles (45.4%) in patients and 1326 of 2704 alleles (49.0%) in controls (p = 0.037). This frequency in EU was 36 of 60 alleles (60%), which was higher than that observed in patients from phase I (p = 0.018) and phase II (p = 0.027). The LDLRAP1-mRNA expression was lower in AA carriers than in non-AA carriers (median [Q1-Q3]: 0.85 [0.17-1.75] relative-units [ru] versus 1.71 [1.00-2.73] ru; p = 0.041). Our results suggest that LDLRAP1-rs4075184-A allele is associated with lower susceptibility to HCV-infection and with reduced expression of LDLRAP1-mRNA.
