Epidemiological characteristics of HIV and AIDS in mainland China: a 16-Year national surveillance analysis (2005-2020).
Article in BMC infectious diseases, 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
backgroundThis study aimed to describe the epidemiological trends and regional/age distributions of HIV and AIDS in China from 2005 to 2020 and provide scientific reference for the government about HIV and AIDS prevention and control.
methodsData on HIV and AIDS cases reported encompassing various age groups and 31 provinces, autonomous regions, and municipalities in mainland China from 2005 to 2020 were sourced from the Data Center of China Public Health Science.
resultsA total of 570,576 AIDS cases were identified and reported in China from 2005 to 2020. The reported AIDS incidence, AIDS-related mortality, HIV incidence, and HIV mortality increased from 0.4324/100,000, 0.1012/100,000, 1.9437/100,000, and 0.0216/100,000 in 2005, respectively, to 4.4283/100,000, 1.3405/100,000, 6.3839/100,000, and 1.2884/100,000 in 2020, respectively. The corresponding average annual growth rates were 16.33%, 18.19%, 7.83%, and 29.40%. The reported HIV and AIDS stage-specific incidence and mortality significantly differed by geography and age. The reported HIV incidence peaked among young adults (20-34 years old), and the > 50 age group showed the highest HIV mortality, AIDS-related mortality and AIDS incidence.
conclusionsThe HIV and AIDS epidemic in China showed a gradual rising trend over the years and exhibited geographical and age distribution difference. Young adults and older populations were the major populations in the HIV and AIDS epidemic in China. Health education, interventions, and testing efforts targeting these key populations should be strengthened. Building a resilient HIV and AIDS treatment service system is essential for ensuring stable HIV and AIDS services during public health emergencies. CLINICAL TRIAL NUMBER: Not applicable.
