Fc-gamma receptor IIA and IIIA variants in two African cohorts: Lack of consistent impact on heterosexual HIV acquisition, viral control, and disease progression.
Article in Virology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Human Fc-gamma receptors (FcγRs) FcγRIIA and FcγRIIIA contain amino acid variants with both high and low affinities for IgG that modulate antibody-mediated effector functions. Recent HIV vaccine trials suggested that these FcγR variants can influence susceptibility to HIV infection, which prompted us to fully assess the role of FcγR variants on HIV acquisition, viral control, and disease progression in two longitudinal heterosexual transmission cohorts with HIV subtypes A and C as the major circulating viruses. For 836 participants, molecular genotyping resolved genetic variations encoding the FcγRIIA (131 H/R) and FcγRIIIA (158 V/F) single nucleotide polymorphisms. Kaplan-Meier curves, Cox proportional hazards models, and linear regression models did not reveal any clear or consistent FcγR association with time to HIV acquisition, viral load in early infection, or extent of CD4 + T-cell decline over time after infection. Overall, previous epidemiological findings on FcγR variants and vaccine efficacy are not readily applicable to heterosexual HIV transmission.
