From: Association between ozone and influenza transmissibility in China
The association between O3 and influenza transmissibility (Rt) of influenza in different provinces (A-H). A-D for four provinces in northern China (Beijing, Tianjin, Liaoning and Gansu), (E–H) for four provinces in southern China (Shanghai, Jiangsu, Guangdong and Hunan). The blue line refers to the R_t, and the gray shading is the 95% confidence interval for the transmissibility
