Table 1. Coefficients for the model Y = b + m∗X + n∗D + k∗(D∗X) presented as Eq. (1) in the text where X is log10-transformed 5-d trimmed N/PMMoV and Y is log10-transformed incidence rate.
Adjusted R-square values and p-values for the model are provided, as well as the F statistic (and the degrees of freedom, DF). Coefficient values with standard errors are reported as well as p-values in parentheses. With Bonferroni corrections, p must be less than 0.0013 for alpha = 0.05. If n is significantly different from 0, then the intercept for the linear relationship between X and Y before and after 1 May 2022 is different and equal to b + n. If k is significantly different from 0, then the slope for the linear relationship between X and Y is different before and after 1 May 2022 and equal to m + k.
