Risk Factors Associated With Incident Dementia in People Living With HIV.
Observational study in Journal of Korean medical science, 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
backgroundCognitive decline often follows human immunodeficiency virus (HIV) infection. The objective of this study was to explore the factors present at HIV diagnosis associated with the risk of incident dementia.
methodsA longitudinal observational study was conducted using a nationwide claim database (2008-2021). A cohort was designed using new diagnosis of HIV infection with antiretroviral therapy. Included in the analysis were individuals aged over 40, with > 3-year follow-up and without a diagnosis of dementia within 2 months post-HIV diagnosis. Dementia was defined as diagnosis and prescription of anti-dementia medication. Cox proportional hazards regression models assessed the association between baseline characteristics and the risk of incident dementia.
resultsAmong the 13,289 HIV-infected cohort, 3,929 met the inclusion criteria. The median age was 45 (interquartile range [IQR], 15), and 90.9% were male. During the median follow-up period of 7.6 (IQR, 5.0) years, dementia developed in 114 patients, with cumulative incidence reaching 4% at the 10-year follow-up. The development of dementia was associated with age at diagnosis ≥ 50 (hazard ratio [HR], 2.31; 95% confidence interval [CI], 1.51-3.53), low socioeconomic status (HR, 3.50; 95% CI, 2.22-5.52), and acquired immune deficiency syndrome (AIDS) status at diagnosis (HR, 2.05; 95% CI, 1.38-3.03).
conclusionThis study underscores the importance of age at HIV diagnosis, socioeconomic status, and AIDS status as determinants of the risk of incident dementia among people living with HIV.
