(A) Rate ratio of ASD-C incidence to ASD-RI and ASD-RN incidence, respectively, according to calendar year. (B) Rate ratio of ASD-C cumulative incidence to ASD-RI and ASD-RN cumulative incidence, respectively, according to birth year. The solid curves are the respective posterior mean estimates for ASD-RI and ASD-RN incidence, while the bands are 95% simultaneous credible bands; 95% of curves from the posterior distribution will fall entirely within these bands.
