Time varying Rt and inferred infection epidemic curve for New York state (a) and risk ratios of each variable to Rt (b). a. Time varying Rt and inferred infection epidemic curve of New York state (NY). The blue bars represent the daily number of infections, the orange lines show the trends of Rt (standard deviation less than 0.5), and the grey shading refers to the 95% confidence intervals of Rt. The dates of the main NPIs executed by NY from February 22 (1 week before the first state emergency on February 29) to April 20 were shown in different colors of triangles. b. Risk ratios (dot) and 95% confidence intervals (bars) of each variable to Rt
