Overall and three-dimensional plots of relative risks with the reference at 15.3 °C. (A) The three-dimensional plot of the association between daily mean temperature (°C) and the effective reproduction number over the lags of 7 days. The reference value of temperature was median temperature (15.3 °C). (B) The estimated overall effects of mean temperature (°C) over 7 days on \(R_{t}\). Blue line shows the mean relative risks, and 95% confidence intervals are shown in the gray shadings.
