“Controlling for possible confounders, either wheeze or daytime or nocturnal attacks of breathlessness were positively associated with SO2, NO2, or formaldehyde.”
Structure
- Factor
- Sulfur dioxide (SO₂)
- Outcome
- Wheeze
- Population

- Study design
- cross-sectional study in a coal-burning city in northern China: a questionnaire on respiratory health and home environment was answered by 1,993 pupils aged 11 to 15 in ten urban schools of Taiyuan, and indoor and outdoor air pollutants and climate factors were measured in the same schools in winter (class 4)
- Caveat
- a stated direction without a coefficient; the sentence names the three pollutants together and ozone is not among them
