Impact of meteorological factors on the incidence of hand, foot and mouth disease in Ningbo from 2014 to 2019: a causal convolutional neural networks.
Article in BMC public health, 2025. 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
backgroundHand, foot, and mouth disease (HFMD) is recognized as a climate-sensitive disease, yet the precise influence of meteorological factors on its incidence remains underexplored. This study leverages Causal Convolutional Neural Networks (Causal CNNs) to investigate the epidemiological characteristics of HFMD in Ningbo City, China, from 2014 to 2019, and to assess the predictive role of meteorological factors, offering novel insights for real-time surveillance and control.
methodsDaily meteorological data and HFMD incidence data for Ningbo from 2014 to 2019 were obtained from the Chinese Center for Disease Control and Prevention. The Causal CNNs and the Granger causality test were applied for prediction and analysis.
resultsFrom 2014 to 2019, the average annual incidence of HFMD in Ningbo was 398.66 per 100,000. The disease showed notable seasonality and annual periodicity, with a bimodal distribution peaking in June-July and October-November each year. The daily mean temperature and relative humidity demonstrated similar annual cyclical variations to HFMD incidence, while daily mean pressure exhibited opposite trends. The Causal CNNs model indicated that daily mean temperature, relative humidity, pressure, and wind speed had better predictive effects with a lag of 19 days [the mean square errors (MSE) were 0.490, 0.333, 0.529, 0.325, respectively, and the mean absolute errors (MAE) were 0.491, 0.355, 0.531, 0.433, respectively]. The Granger causality test confirmed significant correlations between HFMD incidence and daily mean temperature, relative humidity, pressure, and wind speed (The F values were 5.660, 6.878, 4.330, 1.726, respectively, and all P < 0.05).
conclusionMeteorological factors, particularly mean temperature, relative humidity, pressure, and wind speed, may significantly influence HFMD incidence in Ningbo. The Causal CNNs model provides relatively accurate predictions, supporting its potential for enhancing HFMD surveillance and informing targeted public health interventions.
