Figure 2From: Nitrogen dioxide levels estimated from land use regression models several years apart and association with mortality in a large cohort study Comparison of the measurements of NO 2 concentrations taken at the same locations in the two study periods. (A), the ability of 1995/96 model to predict 2007 measurements (B), the ability of 2007 LUR model to predict 1995/96 measurements (C), and the comparison of predicted values of the two LUR models at the addresses of the study population (D).
