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|
|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.
