Associations Between Air Pollution and Hospitalization of Patients with Chronic Obstructive Pulmonary Disease in Kashi, China: A Time-Stratified Case-Crossover Study.

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
Objective: To investigate associations between air pollutants and hospitalization of patients with chronic obstructive pulmonary disease (COPD) in Kashi, and to identify susceptible populations. Methods: We conducted a retrospective study of COPD patients in Kashi between 2012 and 2022. Daily pollutant concentrations were matched to residential addresses for individual exposure assessment. A time-stratified case-crossover design with conditional logistic regression was used to evaluate associations between pollutants and COPD hospitalization. Stratified analyses were performed by age, gender, smoking history and hospitalization season. Sensitivity analysis was conducted by excluding hospitalizations during the COVID-19 pandemic to test result robustness. Results: A total of 68,482 patients were included. The strongest significant association between particulate matter (PM Conclusion: PM
