Midlife hypertension and late-life cognition: weighting the LifeAfter90 study.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 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
introductionMidlife hypertension is a well-established predictor of late-life cognitive decline; however, few population-representative estimates of this association exist among oldest-old cohorts.
methodsLifeAfter90 (LA90) is an ethnoracially diverse cohort of individuals aged 90+ linked to midlife multiphasic health check-ups (MHC). We assessed executive function, semantic memory, and verbal memory at age 90+. We used stabilized inverse probability of censoring weights and linear regression to estimate the association between midlife hypertension and cognitive function in the MHC target population.
resultsAfter weighting, LA90 participants (n = 307) were similar to the MHC population on race/ethnicity, hypertension, and education. Midlife hypertension was not associated with executive function (β = 0.03, [95% confidence interval [CI]: -0.24, 0.31]) and verbal memory (β = -0.10 [95% CI: -0.37, 0.16]). Midlife hypertension was associated with poorer semantic memory (β = -0.19 [95% CI: -0.44, 0.06]). DISCUSSION: People with midlife hypertension averaged lower semantic memory using population-representative models, suggesting that it may have sustained impact on learning and memory in those aged 90+.
