Long-term exposure to air pollution and risk of venous thromboembolism in a large administrative cohort

Table 3 Associations between long-term exposure to air pollutants (PM₁₀, PM_2.5 and NO₂) and deep vein thrombosis (DVT) and pulmonary embolism (PE) in RoLS. Results are expressed as hazard ratios (HR) with relative 95% confidence intervals per 10 µg/m³ increases of pollutant
