Spatial-temporal distribution characteristics of haemorrhagic fever with renal syndrome (HFRS) in 31 provinces and municipalities of P.R. China and multi-factorial prediction of incidence.
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
objectiveTo integrate multi-source spatiotemporal data and construct an HFRS incidence prediction model using XGBoost with SHAP, exploring factors associated with HFRS incidence in China.
methodsCollected HFRS case data from 31 provinces in China (2005-2020) and multi-source data on climate, land use, and population. Used MaxEnt to analyze rodent distribution and key environmental variables. Constructed an XGBoost model integrating climate, land use, host, and socio-economic features, with SHAP values assessing feature contributions. Dataset divided into training (70%), validation (15%), and test (15%) sets, with higher weights for high-incidence provinces.
resultsThe reported HFRS cases in mainland China decreased from 2005 to 2020 but showed seasonal peaks. Cases were mainly among adults aged 20-60 years. The distribution of virus-carrying rodents was mainly affected by minimum temperature of the coldest month and elevation. After removing temporal features, land-use types (forest, cropland, shrub) showed greater relative importance than climate variables.
conclusionForest, shrub, and cropland may affect disease transmission via host distribution and food availability. Climate factors act indirectly on HFRS risk. Temporal features remain critical for incidence prediction, while land use and rodent habitats are key exogenous drivers. These findings support targeted public health strategies.
