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
Brief rationale: dementia and osteoporosis share risk factors and are rising in aging populations. MAIN
resultsosteoporosis significantly increases the risk of all-cause dementia, Alzheimer's disease dementia, and vascular dementia in Korean older women. Significance of the paper: early detection and treatment of osteoporosis may reduce dementia risk. PURPOSE: Dementia and osteoporosis share common risk factors and are increasing in prevalence in the aging population. This study aimed to investigate the impact of osteoporosis on dementia and its subtypes in women using data from a population-based, health-screening cohort, with a follow-up period of more than 10 years.
methodsThis retrospective study included 66-year-old Korean women who participated in the "National Screening Program for Transitional Ages" from 2010 to 2011. Participants were categorized based on spine bone mineral density T-scores into three groups: normal (T-score ≥ - 1.0 standard deviation [SD]; 18.7%), osteopenia (- 2.5 SD < T-score < - 1.0 SD; 42.5%), and osteoporosis (T-score ≤ - 2.5 SD; 38.8%). Incident dementia cases were evaluated until 2021 using national healthcare claims databases. Fine-Gray subdistribution hazard models were used to assess the risks of all-cause dementia including Alzheimer's disease (AD) dementia and vascular dementia (VaD), accounting for death as a competing risk.
resultsThe study included 131,872 dementia-free women aged 66 years. Over an average follow-up of 10.4 ± 1.8 years, 9399 individuals developed all-cause dementia (7.1%). Osteoporosis was associated with increased risks for all-cause dementia (adjusted subdistribution hazard ratio [asHR] 1.14; 95% confidence interval [CI] 1.08-1.21; p < 0.001), AD dementia (asHR 1.14; 95% CI 1.08-1.22; p < 0.001), and VaD (asHR 1.42; 95% CI 1.08-1.87; p = 0.013), compared to normal.
conclusionOur findings highlight an association between osteoporosis and increased risks of developing all-cause dementia, AD dementia, and VaD. Further research is needed to explore the effects of early identification and treatment of osteoporosis in preventing dementia.
