Immune perturbation following SHIV infection is greater in newborn macaques than in infants.
Article in JCI insight, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Transmission of HIV-1 to newborns and infants remains high, with 130,000 new infections in 2022 in resource-limited settings. Half of HIV-infected newborns, if untreated, progress to disease and death within 2 years. While immunologic immaturity likely promotes pathogenesis and poor viral control, little is known about immune damage in newborns and infants. Here we examined pathologic, virologic, and immunologic outcomes in rhesus macaques exposed to pathogenic simian-human immunodeficiency virus (SHIV) at 1-2 weeks, defined as newborns, or at 4 months of age, considered infants. Kinetics of plasma viremia and lymph node seeding DNA were indistinguishable in newborns and infants, but levels of viral DNA in gut and lymphoid tissues 6-10 weeks after infection were significantly higher in newborns versus either infant or adult macaques. Two of 6 newborns with the highest viral seeding required euthanasia at 25 days. We observed age-dependent alterations in leukocyte subsets and gene expression. Compared with infants, newborns had stronger skewing of monocytes and CD8+ T cells toward differentiated subsets and little evidence of type I interferon responses by transcriptomic analyses. Thus, SHIV infection reveals distinct immunological alterations in newborn and infant macaques. These studies lay the groundwork for understanding how immune maturation affects pathogenesis in pediatric HIV-1 infection.
