Table 5. The cumulative extreme effects of meteorological variables on mumps incidence along the lag days.

Meteorological variables	RR(95%CI)
Meteorological variables	Effect of extremely high value^a	Effect of extremely low value^b
Mean temperature	1.81 (1.41, 2.32)	0.61 (0.41, 0.91)
Relative humidity	1.28 (1.02, 1.59)	0.79 (0.59, 1.07)
Wind velocity	0.99 (0.78, 1.27)	0.70 (0.54, 0.91)
Atmospheric pressure	0.80 (0.67, 0.95)	1.00 (0.90, 1.11)

^a The effects of an extremely high value were presented by the RR of the meteorological variables on the incidence of mumps by comparing the 99th to the 90th percentile of each variable. ^bThe effects of an extremely low value were presented by the RR of the meteorological variables on the incidence of mumps by comparing the 1th to the 10th percentile of each variable.
