Table 2 Significance of the difference between mean excess CVD mortality associated with cold spells and on the other days in November-March excluding epidemics, for the same age groups and lags as in Table 1.

From: Excess cardiovascular mortality associated with cold spells in the Czech Republic

Population group Mean excess CVD mortality associated with cold spell days
[deaths/day]
Mean excess CVD mortality on other days in winter (Nov.-March)
[deaths/day]
p value of the t-test for the difference in means
All ages, M 5.4 -0.2 < 0.001
All ages, F 6.5 -0.2 < 0.001
25–59 yrs, M 1.7 0.0 < 0.001
25–59 yrs, F 0.3 0.0 0.178
60–69 yrs, M 0.7 -0.1 0.083
60–69 yrs, F 0.8 -0.1 0.009
70–79 yrs, M 1.9 0.1 0.001
70–79 yrs, F 2.3 0.2 < 0.001
80+ yrs, M 2.2 -0.2 < 0.001
80+ yrs, F 4.2 -0.3 < 0.001
  1. Two sample t-test was used for testing the difference in means.
