Plasma Inflammatory Biomarkers Lack Strong Association With Cognitive Outcomes Among Young Adults With Perinatal HIV Exposure and/or Acquisition.
Article in Journal of acquired immune deficiency syndromes (1999), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundOur objective was to evaluate the association between inflammatory biomarkers and NIH Toolbox cognitive outcomes in young adults with perinatal HIV exposure but uninfected (YAPHEU) and those with perinatal HIV (YAPHIV), with or without prior HIV disease progression.
settingWe analyzed participants with plasma samples and NIH Toolbox cognitive scores at entry into a multisite longitudinal cohort in the United States.
methodsParticipants were subdivided into groups by HIV status: YAPHIV who experienced a stage 3 event (YAPHIV-W3, indicating history of HIV disease progression), YAPHIV who had not (YAPHIV-WO3), and YAPHEU. Fifteen biomarkers were measured. Principal component analysis was used to derive biomarker principal component (PC) scores, with 4 PCs retained, accounting for 67% of the variance within biomarker correlations. We computed Pearson correlations of individual log-transformed biomarkers and PCs with NIH Toolbox Total, Fluid, and Crystallized Cognition Composite Scores, separately by HIV status.
resultsA total of 638 participants (135 YAPHIV-W3, 383 YAPHIV-WO3, 117 YAPHEU, and 3 YAPHIV without stage 3 information) met eligibility criteria. The median age was 20.6 years (Interquartile Range 18.6-24.6), and 60% (n = 381) were female. In both YAPHIV-WO3 and YAPHIV-W3, PC3 was weakly negatively correlated with Fluid and Total Cognition Composite Scores. In YAPHIV-W3, PC2 was also weakly negatively associated with Fluid Cognition. In YAPHEU, PC1 was weakly positively correlated with Fluid Cognition and weakly negatively correlated with Crystallized Cognition.
conclusionsNo inflammatory biomarkers or summary score measures showed meaningful associations with worse cognitive outcomes in a population with long-term perinatal HIV acquisition or exposure.
