Kaplan–Meier plot showing time to screening for the intervention and control arms for the various sampling approaches. The distance between ‘Conventional screen (intervention)’ (dashed blue line) and ‘Any screening test (Intervention)’ (solid red line) is the additional uplift in screening from non-speculum clinician sampling and self-sampling. The difference between the ‘Self-sample or conventional screen (intervention)’ (red dashed line) and ‘Any screening test (intervention)’ (red solid line) represents the number of women with a non-speculum clinician-taken sample. All screening in the control arm is conventional (speculum) screening as this is the only screening method currently available in the England national screening programme.
