Environmental and State-Level Regulatory Factors Affect the Incidence of Autism and Intellectual Disability
Figure 5
Total county-level random effects of ASD and ID incidence in the USA: (A) ASD and (B) ID.
In the figures we color-coded the Empirical Bayes estimates of the state-level random effects, separately for ASD and ID. While county-specific random effects are directly comparable within the same state, comparison of these effects across different states is not meaningful, because each state-specific random effect determines the baseline disease rate for each county in the corresponding state, and these baseline rates vary across states.
