Aging with HIV: The Interplay of Neighborhood-Level Social Vulnerability, Social Support, and Physical Activity.
Article in AIDS and behavior, 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
Engaging in moderate-to-vigorous physical activity (MVPA) is essential for healthy aging in people with HIV (PWH), though social determinants may influence activity levels. This cross-sectional study examined associations between neighborhood social vulnerability, social support, and MVPA among 198 PWH aged ≥ 50 from the PROSPER-HIV study across four U.S. sites. MVPA was measured with ActiGraph accelerometers (minutes/week), social vulnerability with the Social Vulnerability Index (SVI), and social support with the Multifactorial Assessment of Perceived Social Support-Short Form. Linear regression models were used to estimate the associations between study variables, adjusting for age, sex, and site. Median MVPA was 110 min/week (IQR: 48.03-237.05). Higher SVI was associated with MVPA in unadjusted models but did not reach statistical significance (β= -1.77; p = 0.053), and this association was attenuated after adjustment (p = 0.20). Social support was not associated with MVPA. Findings highlight the need for larger studies using more precise measures of structural factors relevant to physical activity among older PWH.
