Table 2: Percentage increase (95% CI) in mortality for 1 °C decrease in mean temperature on extreme cold days (and following seven consecutive days) and its association with sex and age.
% Increase | 95% CI | P | |
---|---|---|---|
All-cause death | 8.6 | 1.074-1.097 | < 0.001 |
Sex | 8 | 0.860-0.982 | 0.012 |
Age (> 70 yrs) | 2.3 | 1.136-1.321 | < 0.001 |
Regression analyses were conducted on extreme cold day's temperature and following days; an offset was added in the model to mould mortality rates per year-by-season-by-month.
