Figure 1:
Association between PM2.5 (continuous variable) and hazard ratio (Log) of primary outcome in in the intensive vs standard BP in the (A) entire cohort (n=9,286) and (B) excluding PM2.5≤3 μg/m3 (n=8,718). PINTERACTION is between PM2.5 and study assignment. The association between PM2.5 and primary outcome was not statistically significant in the standard arm or the intensive arm.
