*Per cent change in mortality on extreme temperature days relative to all other days.
†For cold exposure, this refers to per cent change in mortality per each degree of maximum daily temperature below 17°C; for heat exposure, this refers to per cent change in mortality per each degree of minimum daily temperature above 17°C.
