A rare null allele potentially encoding a dominant-negative TRIM5alpha protein in Baka pygmies.
Article in Virology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The global acquired immunodeficiency syndrome (AIDS) pandemic is thought to have arisen by the transmission of human immunodeficiency virus (HIV-1)-like viruses from chimpanzees in southeastern Cameroon to humans. TRIM5alpha is a restriction factor that can decrease the susceptibility of cells of particular mammalian species to retrovirus infection. A survey of TRIM5 genes in 127 indigenous individuals from southeastern Cameroon revealed that approximately 4% of the Baka pygmies studied were heterozygous for a rare variant with a stop codon in exon 8. The predicted product of this allele, TRIM5 R332X, is truncated in the functionally important B30.2(SPRY) domain, does not restrict retrovirus infection, and acts as a dominant-negative inhibitor of wild-type human TRIM5alpha. Thus, some indigenous African forest dwellers potentially exhibit diminished TRIM5alpha function; such genetic factors, along with the high frequency of exposure to chimpanzee body fluids, may have predisposed to the initial cross-species transmission of HIV-1-like viruses.
