Hazard Ratios from the simulated data with time varying PM2.5 exposure following linear pattern.
(a) with a one year lag between PM2.5 exposure and outcome and (b) based on the cumulative average. Boxplots shows median, IQR and range of the estimated HRs from each of the 1000 simulations for each exposure metric.
