Features of the land use and COVID-19 cases and deaths in urban and land counties in Poland throughout the pandemic: a machine learning approach.
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
backgroundThe research shows the impact of land use forms and population density on the spatial variation of COVID-19 cases and deaths. Selected elements of land use that influence the number of COVID-19 cases and deaths were explored using an analysis of public data sets from 380 administrative units in Poland, which covered the entire pandemic period (from March 2020 to June 2023). This association has yet to be systematically elucidated with a machine learning method.
methodsA machine learning model based on the structure of a multilayer artificial neural network was applied. Three independent models were developed to forecast COVID-19 cases and deaths and the case fatality ratio based on the type of county, population density and selected forms of land use (agricultural land, forest land, built-up urbanized, recreational, residential, transport and industrial). A global sensitivity analysis calculations were performed.
resultsThe results show clear differences in COVID-19 rates between urban and land counties, which well reflects the impact of land use. The best results for COVID-19 case forecasting were obtained with the model consisting of 12 neurons in the hidden layers and the hyperbolic tangent activation function for the test set: R2 = 0.977, MAE = 1596.8 people, and RMSE = 4158 people. The highest consistency of the COVID-19 death forecasts was obtained with the model consisting of 11 neurons and the sigmoid activation function in the hidden layers - for the test set: R2 = 0.984, MAE = 26.9 people, and RMSE = 42.3 people.
conclusionThe results demonstrate a high-quality model for predicting viral infections, utilizing the three groups as input data (environmental, socioeconomic, and built environment) and employing artificial intelligence methods. Therefore, it may be a useful tool for analyzing the spread of epidemics. This approach can help national authorities and local governments to mitigate the high risk of infection and mortality in the future.
