Cause	Hot effect*	Cold effect*
	(95%CI)	(95%CI)
Non-accidental	15.46(10.05 to 20.87)	20.39(11.78 to 29.01)
Cardiovascular diseases	20.89(12.24 to 29.54)	23.59(11.33 to 35.85)
Ischemic heart disease	30.01(12.98 to 47.04)	20.95(0.53 to 41.39)
Stroke	15.21(1.39 to 29.03)	11.77(−8.29 to 31.83)
Respiratory diseases	29.82(17.01 to 42.64)	34.82(16.89 to 52.75)
Chronic obstructive pulmonary diseases	21.38(5.56 to 37.20)	25.06(5.07 to 45.04)
All other causes	5.57(−1.43 to 12.57)	10.41(−5.02 to 25.82)

* The effects were presented by percentage increase (%) in mortality risk comparing the 99th to the 90th percentile (hot effect) and the first to the 10th percentile (cold effect) of temperatures.
