Adaptive immune cells and kidney function in older adults: sex-specific associations in the health and retirement study (HRS).
Article in Frontiers in aging, 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
Background: Chronic kidney disease (CKD) is characterized by chronic inflammation and immune dysregulation. Aging of the adaptive immune system, marked by a shift from naïve to memory T-cell phenotypes, is associated with systemic "inflammaging", but sex-specific associations between these immunophenotypes and kidney function in older adults remain poorly understood. Methods: We analyzed cross-sectional data from 8,970 participants (aged ≥56 years) in the 2016 Health and Retirement Study (HRS) Venous Blood Study. Seventeen adaptive immune cell subsets were quantified using multiparameter flow cytometry. Kidney function was assessed using estimated glomerular filtration rate (eGFR, mL/min/1.73 m Results: Females were older and more likely to be never smokers, CMV seropositive, and have lower eGFR, whereas males were more likely to use alcohol, smoke, have diabetes, elevated blood pressure/hypertension and higher educational attainment. In sex-stratified models, higher CD4 Conclusion: Findings suggest that CD8
