The study of the correlation between pollutants and their interactions on the incidence of tuberculosis in Changping District based on distribution models.
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
backgroundAir pollution as a potential risk factor, mediator or moderator of TB incidence. Most of the studies focused on the provincial and urban areas, while Changping District, as a high incidence area and county of tuberculosis in Beijing, its relationship with pollutants is not clear, so this study aims to investigate the associations of air pollutants and their interactions on the number of new TB cases in Changping District, Beijing, China.
methodsData from Beijing Changping Institute for Tuberculosis Prevention and Treatment on monthly new TB cases from 2014 to 2022. Distributed lag nonlinear models are used to examine the associations of each 10 µg/m3 increase in PM10 and NO2 concentrations, along with extreme exposure episodes, with TB incidence.
resultsThe cumulative relative risk (RR) of increasing pollutant concentrations is positively correlated with lag months for PM10, but the opposite result is observed for NO2. In terms of long and short-term relationships, increased PM10 concentration and extremely low NO2 concentration are associated with long-term hazardous for most subgroups, while extremely high PM10 and NO2 concentrations are associated with short-term hazardous.
conclusionIncreased concentrations of PM10 and NO2 having long-term or short-term effects on populations. Therefore, strengthening air quality monitoring and control is of great significance for the prevention of tuberculosis in Beijing.
