1 · What the graph read from it

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.

2 · The registry

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

backgroundAlzheimer's disease and related dementias (ADRD) pose a critical challenge for the aging U.S. population, yet many biological pathways remain unclear. Recent work has focused on whether peripheral immunosenescence contributes to cognitive aging. Using the Health and Retirement Study (HRS), we examined associations between peripheral immunosenescence and domain-specific cognitive function.

resultsImmune function was associated with general and domain-specific cognition, with variation by sex and immune marker. The CD4 + EMRA:Naïve T Cell Ratio, CD4 + Naïve:CD8 + EMRA Ratio, and CMV IgG showed the most consistent associations, particularly with general and executive function. A one-SD increase in CMV IgG was associated with 0.06 SD lower executive function (95% CI: -0.07, -0.05), persisting after adjustment for confounders.

conclusionsAssociations with peripheral immune markers suggest a potential role for peripheral immunosenescence in cognitive aging. The immune system may be an early contributor to cognitive vulnerability, underscoring the need to integrate immune aging into ADRD research.
