Adjusted estimates of the effects of tree cover on AL MAHA by alternative land cover estimation schemes. Model 1: Multiplicative changes in continuous log-transformed AL data; Model 2: Odds ratios for AL above the 90^th percentile of the sample distribution. Effect estimates were adjusted for age, smoking status, education, BMI, density of residential units per census block groups, concentration of NO_x from local traffic, and thin plate spline of geographic coordinates.
