Graph plotting relative risk of mortality (y-axis) in cold, moderate cold, moderate hot, and hot areas across the 12 heat wave definitions (x-axis), namely, 90P underscore 2day, 90P underscore 3day, 90P underscore 4day, 92.5P underscore 2day, 92.5P underscore 3day, 92.5P underscore 4day, 95P underscore 2day, 95P underscore 3day, 95P underscore 4day, 97.5P underscore 2day, 97.5P underscore 3day, and 97.5P underscore 4day. — Cumulative effects of heat waves on mortality over lag 0–10 d in 4 climatic areas (cold, moderate cold, moderate hot, and hot areas) for 12 types of heat wave definitions. Cold areas: mean temperature of hot season: $\leq 20.7 ° C$ ; moderate cold areas: mean temperature of hot season: $20.7 - 24.1 ° C$ ; moderate hot areas: mean temperature of hot season: $24.1 - 27.6 ° C$ ; and hot areas: mean temperature of hot season: $> 27.6 ° C$ . Please refer to Table 1 for heat wave definitions.
