1 · What the graph read from it

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.

2 · The registry

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

objectiveLimited studies have sought to qualify the extent and trends of racial disparities in viral suppression (VS) among people with HIV(PWH) across the Southern US. This study aims to examine the spatiotemporal trend and structural social determinants of racial disparities of VS.

methodsA population-based retrospective cohort study across all counties in South Carolina (SC) from 2013 to 2020. Linear trend test was employed to explore the temporal trend of the disparity indices (Black to White Ratio [BWR], Index of Disparity [ID], Weighted Index of Disparity [Weighted ID], and Gini coefficient). Linear mixed-effect models were further used to assess the association between different contextual factors and these indices.

resultsA decrease in racial disparity in VS (p < 0.01) was observed from 2013 to 2020 across all disparity indices. When measured using Weighted ID and Gini coefficient, lower risk of racial disparities in VS was associated with more Ryan White HIV centers (β = -0.92 and β = -0.0046, respectively) and higher disability rates (β = -1.10 and β = -0.0055, respectively). When measured using ID, Weighted ID, and Gini coefficient, counties in PEE DEE region showed less racial disparities in VS (β = -3.89, -1.73, and -0.0086, respectively, p < 0.05) compared with those in Lowcountry region.

conclusionsAlthough a notable decrease in racial disparities in VS was observed among PWH in SC, attention to addressing related social and structural factors (e.g., fewer Ryan White HIV centers within geographic accessibility) that contribute to poorer HIV outcomes is still needed.
