Mixed Effects Linear Regression Models for the Estimated R_t Before Versus After Relaxation of Social Distancing Measures

	Coefficienta	95% Confidence Interval	P value
Constant term (day prior to relaxation)	.761	.728, .793	<.001
Prerelaxation period (days relative to relaxation)	−.012	−.013, −.012	<.001
Postrelaxation period intercept	.032	.010, .054	.005
Time × postrelaxation period (days relative to relaxation)	.019	.018, .020	<.001
Postrelaxation period (days relative to relaxation)b	.007	.006, .007	<.001

^aEstimates adjusted for day of the week and population density.

^bThe postrelaxation term represents the linear combination of the prerelaxation period and the time × postrelaxation period coefficient.
