The cumulative effects of high and low temperatures on cause-, age-, and sex-specific mortality

Statistic	High temperature effecta (95% CI)	Low temperature effectb (95% CI)
All-cause mortality	1.28 (1.04–1.58)*	1.78 (1.10–2.88)*
Cause-specific mortality
Non-external	1.32 (1.07–1.63)*	1.88 (1.15–3.07)*
Cardiovascular	1.6 (1.15–2.22)*	1.99 (0.92–4.28)
Respiratory	2.45 (0.91–6.63)	0.47 (0.03–8.19)
Cancer	1.08 (0.69–1.68)	1.71 (0.58–5.05)
Sex-specific mortality
Male	1.28 (0.99–1.67)	1.42 (0.77–2.63)
Female	1.27 (0.95–1.7)	2.19 (1.14–4.21)*
Age-specific mortality
0–64 years old	1.05 (0.76–1.46)	1.43 (0.65–3.14)
≥65 years old	1.42 (1.11–1.83)*	2.0 (1.13–3.52)*

^aHigh temperature effect is the cumulative relative risk comparing the 99th temperature percentile (32.4°C) to the 50th temperature percentile (26.3°C) at lag 0–2.

^bLow temperature effect is the cumulative relative risk comparing the 1st temperature percentile (15.8°C) to the 50th temperature percentile (26.3°C) at lag 0–28.

^*Significant at p<0.05.
