Figure 5From: Impact of exposure measurement error in air pollution epidemiology: effect of error type in time-series studies Percent attenuation in risk ratio per unit of measurement (ppm) and per IQR for CO error simulations ( = 0.411) with incremental changes in error type ranging from type B ( σ In Z / σ In Z* = 0.65) to type C ( σ In Z / σ In Z* = 1.55). Bars denote standard deviations for 1000 simulations.Back to article page
