Air pollution and mortality in acute lymphoblastic leukemia patients across different age groups in Northern Thailand (1999-2020).
Article in PloS one, 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
This study investigated the impact of air pollution on 604 patients diagnosed with acute lymphoblastic leukemia (ALL) between 1999 and 2020 in upper northern Thailand. Patients were categorized into three age groups: pediatric (<15 years), adolescent and young adult (AYA) (15-39 years), and adult (≥40 years). The cohort included 344 (57.0%) pediatric, 152 (25.1%) AYA, and 108 (17.9%) adult patients, with 5-year survival rates of 64.5%, 19.6%, and 6.7%, respectively. Concentrations of PM2.5, PM10, O₃, and CO were significantly higher in patients who died, particularly among pediatric cases. Among AYA patients, those who died had higher levels of PM2.5, PM10, and CO than survivors. Compared to the pediatric group, the risk of death was higher in AYA (adjusted hazard ratio [aHR]: 3.76) and adult (aHR: 8.10) groups. Patients diagnosed before 2010 had an increased risk of death (aHR: 1.38). Notably, PM2.5 levels ≥50 µg/m³ were associated with increased mortality in pediatric patients. These findings highlight the adverse effects of air pollution on survival outcomes in ALL patients, particularly children under 15 years of age.
