Prevalence and Spatial distribution characteristics of human echinococcosis in Ningxia Hui Autonomous Region, 2011-2023.

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
backgroundEchinococcosis is a zoonotic parasitic disease caused by tapeworms of the genus Echinococcus that endangers public health and hinders socioeconomic development. Ningxia Hui Autonomous Region(Ningxia) is one of the primary locations where this disease is endemic. This study analyzed the prevalence and spatial distribution characteristics of human echinococcosis in Ningxia from 2011 to 2023, providing a reference for identifying key areas of human echinococcosis and developing targeted prevention and control strategies.
methodsData on human echinococcosis in Ningxia from 2011 to 2023 were collected from "China Information System for Disease Control and Prevention". The population data were obtained from the official website of the Ningxia Statistical Bureau. Joinpoint regression analysis was used to characterize the incidence trend of human echinococcosis in Ningxia. County-level electronic maps of Ningxia were downloaded from the National Geographic Information Public Service Platform. The epidemiological characteristics of human echinococcosis were analyzed, and spatial autocorrelation analysis was performed using ArcGIS 10.4 software. Additionally, spatiotemporal scanning analysis was conducted using SaTScan V9.5 software.
resultsA total of 3,316 cases of human echinococcosis were reported from 2011 to 2023.The annual average incidence of the disease was 3.88 per 100,000 persons, with the highest rate of 6.38/100,000 in 2012 and the lowest rate of 1.33/100,000 in 2023. The incidence rate of human echinococcosis showed a declining trend, with average annual percent change (AAPC) of -11.27% (95% CI: -15.50% to -6.83%; t = -4.80, P < 0.001). Of the total cases, 1,566 were male and 1,750 were female. The male-to-female ratio is 0.89:1, with the incidence rate lower in males (3.48 per 100,000) than in females (4.06 per 100,000). The incidence rate was highest in the 70-year age group (17.00 per 100,000), followed by the 60-year age group (10.84 per 100,000), while the lowest incidence was observed in the 0-year age group (0.09 per 100,000). These data demonstrate a clear age-dependent increasing trend in human echinococcosis incidence rate(χ
conclusionThis study is based on Ningxia's echinococcosis surveillance data from 2011 to 2023. It was confirmed through spatial epidemiological analysis that the national central transfer payment prevention and control project can effectively reduce the rate of echinococcosis infection in the population. The spatial clustering characteristics found in the study (high-high clustering areas are concentrated in the southern mountainous areas, and low-low clustering areas are located in the northern and central areas) provide a scientific basis for differentiated prevention and control strategies. It is recommended to use "patient tracking + key population monitoring" instead of whole-region screening, focusing health resources on key areas and key populations, and maximizing prevention and control efficiency.
