Additional file 1: of Mortality effects of heat waves vary by age and area: a multi-area study in China

Table S1. Introduction of Chinese Air Pollution Index (API). Table S2. Heat wave definitions with different metric, threshold and duration in this study. Table S3. Akaike Information Criterion (AIC) values for models examining HWII–mortality relationships over lag 0–3 days by 16 heat wave definitions in the studied areas during 2007–2012. The values in orange are the minimum AICs in each area. Table S4. Akaike Information Criterion (AIC) values for models examining HWII–mortality relationships over lag 0–3 days by different degrees of freedom (df) for HWII and days for lag in the studied areas during 2007–2012. The values in orange are the minimum AICs in each area. Figure S1. Include API (a), maximum temperature (b) and minimum temperature (c) separately in the HWII–mortality models for different age groups in the studied areas over lag 0–3 days, the shaded areas represent 95% confidence intervals. Figure S2. Monthly averages of both API and HWII from 2007–2012 in the studied areas. Figure S3. The HWII–mortality relationships for different age groups in the studied areas over lag 0–5 days (a), 0–7 days (b) and 0–10 days (c), the shaded areas represent 95% confidence intervals (DOC 23835 kb)
