Mortality ratios of all-cause mortality for income quintiles adjusted for age, education, socioeconomic status, economic activity and living alone in 1988–1991, 1996–1999 and 2004–2007, women aged 35–64 years

↵* Change in excess mortality is calculated as follows: ((RR in M4 − RR in M1))/((RR in M1) − 1)×100.
ALONE, living alone; ECON, economic activity; EDU, education; SES, occupational social class.
