Table III.
The effect of the intervention on awareness of CT and HRA, knowledge of CT and willingness to participate in a CT during the first follow-up (n=305).

Risk ratios compare the intervention vs. control groups at the first follow-up (control group used as reference);
**
Risk ratios adjusted by outcome at baseline, sex, age, and being diagnosed with anal cancer scares me at baseline.
