Kidney Function, Cognitive Impairment, and Trajectories: A Longitudinal Biracial Study.
Article in Journal of general internal medicine, 2025. 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
backgroundChronic kidney disease (CKD) is associated with incident cognitive impairment (ICI) and disproportionately affects older adults and Black persons.
objectiveTo determine (1) whether age or race differences exist in the association of CKD and ICI and (2) whether cognitive trajectories differ in people with and without CKD.
designNationwide cohort study.
participantsA total of 22,435 Black and White adults age ≥ 45 years without baseline cognitive impairment. MEASUREMENTS: Creatinine-cystatin C-based eGFR and albumin-to-creatinine ratio (ACR). Six-item screener (SIS) of global cognition every 6 months, three cognitive domain tests (memory, semantic, and letter fluencies) every 2 years for 10 years. Logistic regression for risk of CI and latent growth curve models for trajectory analysis.
resultsParticipants were 56% female, 37% Black, 56% hypertensive, and 19% had diabetes. Overall, 13% (n = 2959) developed ICI over 10 years. In mid-life (age 45- < 65), the OR (95% CI) of ICI for eGFR < 45 vs eGFR ≥ 90 was 1.9 (1.2, 3.0); in late-life (≥ 65), the OR was 0.9 (0.7, 1.1), p interaction < 0.001. For ACR > 300 vs ACR < 10, in mid-life and late-life, the ORs were 1.6 (1.0, 2.6) and 1.0 (0.7, 1.4), p interaction 0.02. Compared to those with eGFR ≥ 60, eGFR < 60 was associated with lower initial cognitive domains scores, worse in mid-life than late-life, but the slopes did not differ. Compared to ACR < 30, ACR ≥ 30 had lower initial cognitive domain scores, which were similar in mid and late-life, and a steeper decline for memory scores. No differences by race were observed.
conclusionsKidney disease was more strongly linked to cognitive impairment in mid-life than in late-life. Albuminuria was associated with steeper decline in memory function, especially in mid-life. PRIMARY FUNDING SOURCE: NIGMS.
