RESULTS
Overall, 568 women were screened for eligibility between July 2021 and February 2022; 286 women consented to participate in the trial, 143 were randomised to receive the intervention and 143 were randomised to the control group (Figure CONSORT flow diagramBaseline characteristics were largely similar between the intervention and control groups and are presented in Table Baseline characteristicsAbbreviations: GCE: General Certificate of Education; GCSE: General Certificate of Secondary Education.In total, 69.8% of women in the intervention group made an informed choice compared with 53.6% in the control group (Risk Ratio, RR, 1.30 [95% Confidence Interval, CI, 1.05–1.61] Of the 51 participants who made an uninformed choice in the control group, poor knowledge was found to be the cause in 64.7% of participants, value‐inconsistent behaviour in 15.7% and both poor knowledge and value‐inconsistent behaviour in 19.6%. Of the 35 patients who made an uninformed choice in the intervention group, poor knowledge was found to be the cause in 48.5% of participants, value‐inconsistent behaviour in 37.1% and both poor knowledge and value‐inconsistent behaviour in 14.3%.Regarding test uptake, 37.7% of women in the control group chose not to test compared with 41.5% in the intervention group. The breakdown of test uptake is shown in Table Test uptakeTwo subjects in the control group and one subject in the intervention group did not make a decision.When subgroup analyses were performed for the primary outcome, informed choice was significantly higher in the intervention group in women aged <35 years (RR 1.35, [95% CI 1.08–1.70], Subgroup analyses
