Hormone replacement therapy and dementia risk among postmenopausal women: Identifying responsive subgroups in the UK Biobank.
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
introductionModifiers of the association between hormone replacement therapy (HRT) use and dementia risk and responsive subgroups, are unknown.
methodsIn 183,450 postmenopausal women from the UK Biobank (mean 13.3 years follow-up), multivariable Cox regression models evaluated associations between HRT use (≥1 year) and all-cause dementia and dementia subtypes. Stratified analyzes assessed modification by menopause type, lifetime estrogen exposure, apolipoprotein E (APOE) ɛ4 genotype, and age at HRT initiation.
resultsOver 2.43 million person-years, 3,948 dementia cases were identified. HRT use was associated with lower all-cause dementia (hazard ratio [HR] 0.90; 95% CI, 0.84-0.96), with stronger associations in surgical menopause (0.74, 0.65-0.84), APOE ɛ4 carriers (0.87, 0.80-0.95) and women with lower endogenous estrogen exposure (0.84, 0.77-0.93). Initiation between ages 46 and 56 conferred the greatest benefit. DISCUSSION: HRT use was associated with lower dementia risk, and these findings may help inform more tailored approaches to HRT prescribing in relation to women's lifetime dementia risk.
