Development of a progressive HIV-1-Like infection model in northern pig-tailed macaques using stHIV-1sv/G53D.
Article in Emerging microbes & infections, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Simian immunodeficiency virus (SIV) and simian-human immunodeficiency virus (SHIV) infections in nonhuman primates closely approximate human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), but intrinsic viral differences limit translational relevance. A physiologically accurate HIV-1 model remains elusive. Here, we established a progressive HIV-1-like infection model using northern pig-tailed macaques (NPMs) infected with stHIV-1sv/G53D and monitored for 200 days. Results showed persistent viremia, progressive CD4+ T-cell depletion, and influenza-like symptoms, mirroring clinical features of HIV-1 infection. Infected macaques recapitulated T-cell exhaustion, innate immune activation, chronic immunosuppression, multi-organ biomarker alterations, and microbial dysbiosis. Transient and attenuated antiviral immunity may underlie this disease trajectory. In summary, this model serves as a complementary platform for validating direct antiviral strategies targeting HIV-1.
