Table 3 Relative risk of group-specific mortality on heat-wave days compared with non-heat-wave days (using heat wave definition HW14, HW29, HW43, and HWCMA) with and without adjusting for air pollutants in Wuhan, China during 2003–2010

From: Global climate change: impact of heat waves under different definitions on daily mortality in Wuhan, China
