Statistical analysis
REGRESSION
Quantitative data was analysed with SPSS vs 24. Descriptive statistics at baseline were reported as mean (SD) for continuous data and frequencies (percentages) for categorical data. Differences in screening uptake between the IG and CG was assessed using regression analysis (adjusting for ethnicity). A Chi-square test compared the proportion of IG and CG participants who attended CBE after the intervention had been delivered, approximately 4–6 weeks after completing the survey. Unadjusted and adjusted odds ratios were calculated using logistic regression; and linear regression was used to generate unadjusted and adjusted mean differences with 95% CIs for the screening intention score. Further regression analyses investigated the influence of factors (e.g. ethnicity, age, income, marital status, education, monthly family income and study area) in terms of affecting screening participation.
