Figure 4From: Impact of exposure measurement error in air pollution epidemiology: effect of error type in time-series studies Percent attenuation in risk ratio per ppm (left panel) and per IQR (right panel) due to error versus population-weighted semivariance. Bars denote standard deviations for 1000 error simulations. Pollutant labels are in order of increasing population-weighted semivariance.Back to article page
