Epidemiological trends and comparative forecasting models of human brucellosis in inner mongolia autonomous region, mainland China, 2004-2024.
Article in PLoS neglected tropical 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
introductionBrucellosis remains a severe zoonotic threat in the Inner Mongolia Autonomous Region of China. METHODOLOGY: This study integrates a comprehensive epidemiological trend analysis with a novel methodological comparison of forecasting techniques to inform control strategies.
resultsUsing reported human brucellosis surveillance data from Inner Mongolia for 2004-2024, joinpoint regression analysis revealed a persistently increasing yet fluctuating long-term trend (AAPC = 5.13%, P < 0.001), characterized by significant epidemic surges in 2004-2010 (APC = 22.43%, P < 0.001) and 2016-2021 (APC = 29.83%, P < 0.001), interrupted by a decline phase in 2010-2016 (APC = -17.17%, P < 0.001) and 2021-2024 (APC = -12.15). The disease demonstrated strong seasonality with June-August peaks, and predominance among farmers and herdsmen aged 30-60 years. Building on this epidemiological foundation, we rigorously compared the predictive performance of the standard Seasonal Autoregressive Integrated Moving Average (SARIMA) model against its Bootstrap-enhanced version for 24-month-ahead forecasting (2023-2024 validation). This finding offers a novel perspective on enhancing the predictive performance of brucellosis models. While the Bootstrap approach achieved superior point forecast accuracy by reducing Mean Absolute Error by 39.95% and Median Absolute Percentage Error by 33.55% compared to SARIMA, it produced severely overconfident prediction intervals, with only 33.33% empirical coverage compared to SARIMA's 91.67%. This study validates the SARIMA model as a robust baseline for brucellosis forecasting and introduces a Bootstrap ensemble method as a powerful tool for significantly enhancing point prediction accuracy.
conclusionThe findings provide novel epidemiological insights that offer a scientific basis for disease control measures and decision-making. Future work should aim to develop hybrid models that bridge this gap, and delivering high accuracy in both point and interval forecasts.
