Article in Respiratory research, 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
backgroundLimited research has investigated the association between particulate matter (PM2.5 and PM10) air pollution and cardiorespiratory diseases. This study aimed to quantify the association between short-term exposure to PM2.5 and PM10 and the frequency of emergency department (ED) visits for cardiorespiratory conditions in Taiwan during the year 2016.
methodsIn this work, we examined administrative areas in northern Taiwan. Emergency department visits records, from January to December 2016, were obtained from longitudinal Health Insurance Database 2000 (LHID:2000), provided by the National Health Insurance (NHI), which administrates all hospitals in Taiwan. We used the CMAQ model to estimate PM concentrations, and weather variables were also collected during the study period. A time-stratified case-crossover design, along with conditional logistic regression models, was employed to assess the association between short-term exposure to PM2.5 and PM10 and ED visits across several counties.
resultsA total of 688,324 ED visits records were collected. Of these, 334,325 visits by males and 353,999 by females. Exposure to PM2.5 and PM10 was associated with an increased frequency of cardiorespiratory ED visits. An interquartile range (IQR) increase in PM2.5 concentration at lags of 0, 3, and 4 days was significantly associated with an increased incidence of asthma, with odds ratios (ORs) of 1.09 (95% CI 1.02–1.17), 1.06 (95% CI 1.00–1.14), and 1.08 (95% CI 1.02–1.16), respectively. A significant association was observed between PM10 and asthma incidence at lags of 0 and 4 days, with ORs of 1.14 (95% CI 1.03–1.26) and 1.12 (95% CI 1.02–1.24). Conversely, no significant association was observed between PM exposure and the incidence of chronic obstructive pulmonary disease (COPD) and ischemic heart disease (IHD).
conclusionThese findings underscore the short-term effects of PM2.5 and PM10 on ED visits for cardiorespiratory diseases. An increasing trend in asthma occurrence was identified across counties at different lag days, which may help guide air pollution control measures and disease prevention strategies in the region.
