Association between ambient air particulate matter and serum thromboxane (Tx)B2 levels modified by COPD status. Shown are percent changes (95% CIs) in serum TxB2 levels per 103/cm3 increase in UFPs and per 10 μg/m3 increase in PM2.5 during the 1–14 days preceding the clinical visits. Based on the linear mixed-effects models, interaction terms (COPD status and pollutant concentration) were added to calculate the estimates within each group and Pinteraction for the effect modification. The significant between-group differences with Pinteraction < 0.05 were indicated by asterisks
