Estimates are predicted rates after Poisson regression reported with robust standard errors clustered at the state level. Regression adjusted estimates include all covariates listed in Table 1 and the natural log of time elapsed since first case (in days). Statistical significance of predicted rates is with respect to a null hypothesis of 0. Statistical significance of relative rates is with respect to a null hypothesis of 1.0.
