Table 3 Age-adjusted odds ratios (95% confidence intervals, CI) of participation in cervical cancer (30–59-year-olds) and breast cancer screening (50–59-year-olds) in 1998 and proportions (%) of localised cancers among 20–64-year olds (1996–1998) in three groups, formed by the rate of private gynaecologist visits in 5-year-age groups in 1999 1).
