Hypertension control and risk of age-associated dementia in people with HIV infection.

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
objectiveHypertension is a major risk factor for dementia, but sustained blood pressure control is difficult to achieve. We evaluated whether inadequately controlled hypertension may contribute to excess dementia risk among people with HIV.
designA retrospective cohort study.
methodsWe studied demographically matched people with and without HIV between July 1, 2013, and December 31, 2021, who were at least 50 years old and had a hypertension diagnosis but no dementia diagnosis. Hypertension control was calculated using a disease management index (DMI), which captured degree and duration above the hypertension treatment goals of SBP less than 140 mmHg and DBP less than 90 mmHg. DMI values ranged from 0 to 100% (perfect control); hypertension was considered 'inadequately controlled' if DMI was less than 80% (i.e., in control for <80% of the time). Annual, time-updated DMI was calculated for SBP and DBP. Associations of SPB and DPB control with incident dementia were evaluated using extended Cox regression models.
resultsThe study included 3099 hypertensive people with HIV (mean age: 58.3 years, 90.2% men) and 66 016 people without HIV. Each year of inadequate SBP control was associated with greater dementia risk in both people with HIV (adjusted hazard ratio [aHR] = 1.26, 0.92-1.64) and people without HIV (aHR = 1.27 (1.21-1.33); P- interaction = 0.85). Similarly, inadequate DBP control was associated with greater dementia risk in both people with HIV (aHR = 1.43, 0.90-1.95) and people without HIV (aHR = 1.71, 1.50-1.93; P -interaction = 0.57).
conclusionFindings suggest the association of inadequate hypertension control with greater dementia risk is similar by HIV status. Stronger associations of DBP control with dementia merit further investigation.
