Susceptibility to repeated, low-dose, rectal SHIVSF162P3 challenge is independent of TRIM5 genotype in rhesus macaques.
Article in AIDS research and human retroviruses, 2013. 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
Infections following repeated, low-dose (RLD), mucal S(H)IV exposures of macaques are used to model sexual HIV exposures for biomedical prevention testing. Different susceptibilities among animals can complicate study designs. In rhesus macaques, TRIM5 alleles Q, CypA, and TFP are resistance factors for infection with some S(H)IV strains, but not for SIVmac239 due to its capsid properties. SIVmac239-derived SHIVSF162P3 has been demonstrated to reproducibly infect mucosally in vaginal and rectal RLD models. To further test the suitability of SHIVSF162P3 for RLD models, we studied the influence of the TRIM5 genotype on susceptibility to rectal RLD infection and on plasma viremia by analyzing 43 male Indian rhesus macaques from control arms of completed studies. The median number of exposures required for infection was three (Q/Q, n=4) (TRIM5 alleles, number of macaques, respectively), four (Q/CypA, n=7), three (TFP/Q, n=15), three (TFP/TFP, n=15), and two (TFP/CypA, n=2); TRIM5(CypA/CypA) was not represented in our study. Median peak viremia (log10 viral copies/ml) in infected animals was 7.4 (Q/Q, n=4), 7.2 (Q/CypA, n=6), 7.3 (TFP/Q, n=13), 7.1 (TFP/TFP, n=15), and 6.5 (TFP/CypA; n=2). Neither susceptibility nor peak viremia was significantly different (log rank test, Kruskal-Wallis test, respectively). Rhesus macaques' susceptibility to RLD SHIVSF162P3 is independent of the TRIM5 TFP, CypA, and Q alleles, with the limitation that the power to detect any impact of CypA/CypA and TFP/CypA genotypes was nonexistent or low, due to absence or infrequency, respectively. The finding that TRIM5 alleles do not restrict mucosal infection or ensuing replication rates suggests that SHIVSF162P3 is indeed suitable for RLD experimentation.
