Spatiotemporal heterogeneity and influencing factors of hepatitis B in China: a 17-year national surveillance analysis.
Article in BMC public health, 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
backgroundHepatitis B remains a major global public health concern, and China bears one of the heaviest burdens worldwide. However, existing research on factors influencing hepatitis B incidence in China remains insufficient, with limited attention paid to educational, environmental, and meteorological factors.
methodsData on hepatitis B incidence were obtained from the Public Health Science Data Center. Spatial correlation analysis was performed using GeoDa 1.20 software, and a geotemporally weighted regression (GTWR) model was applied to examine spatial heterogeneity in the incidence of hepatitis B.
resultsBetween 2004 and 2020, hepatitis B incidence in China exhibited a decreasing trend and significant seasonality, peaking in March. Spatially, incidence was lower in the eastern regions and higher in the western regions, particularly in Tibet and Xinjiang, indicating marked spatial heterogeneity. High-high clusters were primarily concentrated in Guangdong, whereas low-low clusters were identified in Jiangsu and Shanghai. NDVI and the number of licensed (assistant) physicians per 1,000 population were positively associated with hepatitis B incidence, while the number of healthcare beds per 1,000 population and the illiteracy rate were negatively associated.
conclusionsThis underscores the importance of formulating hepatitis B policies in light of local conditions. Priority should be given to high-incidence areas such as western China and Guangdong. Government efforts should focus on increasing investment in healthcare resources, enhancing hepatitis B prevention awareness among the floating population, and expanding vaccination coverage to reduce infection risk. Our findings highlight that geospatial methods can provide crucial insights into optimizing healthcare resource allocation for hepatitis B control and other infectious diseases.
