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

objectivesTo assess the discrepancies between real-world data and the Global Burden of Disease (GBD) 2021 estimates for six neglected tropical diseases in China. Additionally, to evaluate the applicability of the GBD model within the Chinese context and to assess the effectiveness of China's historical prevention and control policies for neglected tropical diseases.

designComparative study of real-world data and GBD 2021 (2004-2020).

main outcome measuresDisability adjusted life years (DALYs).

methodsDALYs based on reported data for leprosy, echinococcosis, schistosomiasis, visceral leishmaniasis, dengue, and rabies from 2004 to 2020 were compared with the estimated DALYs from the GBD 2021 database. Additionally, we combined and analysed China's historical policies on prevention and control of neglected tropical diseases with real-world DALYs. DATA SOURCES: Reported data were sourced from the Chinese Center for Disease Control and Prevention's China Public Health Science data centre and related reports. Data for GBD 2021 and GBD 2019 were obtained from GBD databases. These data included all of China's 31 provinces (including autonomous regions and municipalities) and the Xinjiang Production and Construction Corps.

resultsThe total real-world DALYs based on reported data of six neglected tropical diseases decreased from 260 000 person years in 2004 to 19 000 person years in 2020, with a 93% (241 000/260 000 person years) reduction. The 17 year average real-world DALYs from 2004 to 2020 versus the GBD 2021 estimates for the same period were 42

conclusionsThe findings indicate that reliance solely on global estimates, such as those of the GBD, may not sufficiently capture the dynamics of neglected tropical diseases in China. Integrating local epidemiological data into global health assessments is crucial to develop accurate and effective public health policies. This study highlights the importance of continuously updating and improving data collection and surveillance methods to adapt public health strategies to evolving disease patterns.
