Female	43.8	2.96 (2.13, 3.79)^*	2.77 (1.96, 3.59)^*	2.27 (1.38, 3.17)^*

Cardiovascular mortality
Male	54.75	2.67 (1.63, 3.71)^*	2.12 (1.10, 3.15)^*	0.96 (−0.17, 2.09)
Female	45.25	3.13 (1.98, 4.28)^*	3.24 (2.11, 4.37)^*	2.63 (1.39, 3.86)^*

We applied current-day (lag 0 day) temperature and relative humidity and 2-day moving average of air pollutant concentrations (lag01), and applied 3 df to temperature, humidity and barometric pressure.

P<0.05.
