This systematic review and meta-analysis evaluated the association between air pollution and the risk of hemorrhagic stroke. Analyzing 31 studies, it found that each 10 μg/m3 increase in nitrogen dioxide (NO2) exposure was linked to a risk ratio of 1.0142 for hemorrhagic stroke, while carbon monoxide (CO) exposure had an odds ratio of 1.0008.
Key findings
- Each 10 μg/m3 increase in NO2 exposure was associated with a risk ratio of 1.0142 for hemorrhagic stroke.
- CO exposure showed an odds ratio of 1.0008 per 10 μg/m3 increase.
- The study included 31 eligible studies from an initial 2435 identified.
Why it matters
Understanding the link between air pollution and hemorrhagic stroke risk is crucial for developing preventive strategies. This knowledge can inform public health initiatives aimed at reducing exposure to harmful pollutants.
