Abbreviations: CCS, cervical cancer screening; OR, odds ratio.
a
Random intercept logistic regression adjusted for baseline CCS status in January 2017 for the total sample and in analyses stratified by country of origin. No adjustment in analyses stratified by screening status at baseline.
b
Random intercept logistic regression adjusted for woman’s age, marital status, income level, and region of origin in analyses stratified by screening status at baseline and additional adjustment for baseline CCS status in analyses stratified by country of origin.
c
Random intercept logistic regression adjusted for all covariates in model 2 plus additional adjustment for general practitioner’s sex, age, and region of origin.
