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
Hypertension represents a major public health challenge in sub-Saharan Africa, characterised by substantial underdiagnosis and inadequate management. This secondary analysis of cross-sectional survey data examined the association between physical activity patterns and hypertension prevalence amongst HIV-positive and HIV-negative populations in rural South African communities. Data were drawn from the ongoing Agincourt Health and Socio-Demographic Surveillance System Site (AHDSS), collected between August 2022 and May 2023, involving 4,436 participants aged ≥ 15 years. Physical activity was assessed using the Global Physical Activity Questionnaire (GPAQ) within the WHO STEPwise framework, and blood pressure was measured using an automated digital device (OMRON R6 wrist monitor). Statistical analyses employed chi-squared tests, two-sample t tests, and multivariable logistic regression models adjusting for demographic, anthropometric, metabolic, and behavioural confounders. Moderate physical activity was associated with lower odds of hypertension irrespective of HIV serostatus, supporting the integration of physical activity counselling into HIV care and primary healthcare services in resource-limited settings (adjusted OR = 0.74, 95% CI: 0.56-0.99, p = 0.043). Hypertension prevalence was 40.4% overall. HIV-positive males demonstrated higher prevalence (60.2%) compared with HIV-negative males (46.9%, p < 0.001). HIV-positive status was independently associated with increased odds of hypertension (adjusted OR = 1.45, 95% CI: 1.18-1.78). Age, male sex, obesity, elevated waist-hip ratio, and current alcohol consumption showed significant positive associations with hypertension. Moderate physical activity provides protective benefits against hypertension irrespective of HIV serostatus, supporting the integration of physical activity counselling into HIV care and primary healthcare services in resource-limited settings. Visual summary of key findings. Physical activity and hypertension amongst HIV-positive and HIV-negative populations in rural South Africa: moderate physical activity provides protective benefits against hypertension regardless of HIV status.
