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
backgroundAIDS remains a leading cause of disease burden and mortality worldwide. While traditional research focused on individual risk factors, recent studies emphasize the role of social structures-demographic changes and socioeconomic disparities-in driving spatiotemporal variations in AIDS. This study examines the spatiotemporal distribution of AIDS in Mainland China from 2006 to 2022, analyzing the influence of socioeconomic factors on regional incidence, aiming to inform effective AIDS prevention strategies.
methodUsing AIDS incidence data from 31 Chinese provinces (2006-2022), the study visualizes spatiotemporal trends through incidence rate maps. Spatial autocorrelation analysis identifies clustering patterns, and principal component analysis groups socioeconomic indicators into four dimensions. Kernel density estimation illustrates incidence changes, while Geographically and Temporally Weighted Regression quantifies the spatial effects of development factors on AIDS transmission, highlighting how regional characteristics amplify transmission risks.
resultsThe incidence rate of AIDS in Mainland China increased from 0.51 to 3.69 per 100,000 population between 2006 and 2022, with high-burden clusters mainly in central and western regions. Spatial autocorrelation analysis showed significant clustering patterns (P < 0.05), peaking in 2020 (Moran's I = 0.449). Kernel density estimation revealed rising national incidence trends with regional disparities. Geographically Weighted Principal Component Analysis (GWPCA) identified four key dimensions-economic development, healthcare capacity, transportation, and education-while confirming no multicollinearity. Geographically and Temporally Weighted Regression (GTWR) revealed that transportation infrastructure and healthcare capacity were positively associated with AIDS incidence, particularly in the west, while economic development and education had negative correlations, especially in less-developed western regions.
conclusionThis study reveals spatiotemporal patterns of AIDS distribution in Mainland China and identifies key socioeconomic factors driving these patterns. The incidence rate has steadily increased, with notable regional disparities. Socioeconomic factors significantly influence disease transmission. These findings emphasize the need for targeted interventions and tailored public health strategies in high-risk areas.
