A SYSTEMATIC REVIEW ON THE INFLUENCE OF HLA-B POLYMORPHISMS ON HIV-1 MOTHER-TO-CHILD-TRANSMISSION.

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
backgroundMother-to-child-transmission (MTCT) is the main route of HIV-1 infection in children. Genetic studies suggest HLA-B alleles play an important role on HIV-1 transmission, progression, and control of HIV-1 infection.
objectiveTo evaluate which polymorphisms of HLA-B are involved in HIV-1 MTCT.
methodsTwo independent reviewers performed a systematic review on search engines PubMed, Europe PMC, Cochrane, Scientific Electronic Library Online (SciELO), and Literatura Latino-americana e do Caribe em Ciências da Saúde (Lilacs), using the following key terms: "HIV infection", "HIV newborn", "HLA polymorphisms", "HLA-B", and "Mother to child transmission". All studies focusing on evaluation of HIV-1 MTCT, HIV infection evolution, and molecular analyses of HLA-B in children were selected.
resultsNine studies fulfilled the inclusion criteria. Sixteen HLA-B alleles groups were associated with HIV-1 infection; seven of them (43.8%) were related to slow disease progression or reduced risk of MTCT, while six (37.5%) alleles groups were linked to a faster progression of HIV infection in children and to increased risk of MTCT. The available evidence suggest that HLA-B*57 group allele is associated with slow disease progression, while HLA-B*35 group allele is associated to increased risk of MTCT and rapid disease progression in infected children. The role of HLA-B*18, B*58 and B*44 are still controversial because they were associated to both, protection against MTCT, and to higher HIV replicative capacity, in different studies.
conclusionHLA-B*57 group allele can be protective against MTCT while HLA-B*35 groups alleles are consistently associated with HIV-1 MTCT.
