Effects of temperature on years of life lost from ischemic heart disease in the elderly in Tianjin, China, from 2006 to 2011. The upper panel shows the exposure-response curve between the daily maximum temperature and years of life lost. The bottom panel shows the delayed effects of temperature on years of life lost by lag at cold and heat temperature. The solid line and the grey area show the mean and 95% confidence interval, respectively. -0.3 °C and 33.0 °C are the 5th and 95th percentiles of the daily maximum temperature used to represent cold and heat temperatures, respectively
