The relative risks of different average temperature for HFMD cases at different lags. The 5th percentile values of average temperature (1.7 °C) were defined as the reference for calculating relative risk. The temperature 8.6 °C, 17.8 °C, 24.7 °C and 30.8 °C represented the 25th percentile, 50th percentile, 75th percentile and 95th percentile of average temperature, respectively.
