↵a Follow-up proportions were studied 6 months after a GP reminder — that is, 7 months after recommended date of follow-up for women with a recommendation for gynaecological follow-up within 3 months, and 9 months after date of recommended follow-up for women with a recommendation for follow-up in 3, 6, or 12 months.
↵b Numbers per cervical cytology. Numbers vary due to missing data.
↵c Adjusted for type of follow-up recommendation. Ethnicity, education, and cohabitating status also adjusted for age.
↵d Test for interaction showing if effects of reminders were modified by sociodemographic factors. CI = confidence interval. OR = odds ratio. Ref = reference.
