Hypothesis
Is there an association between marital status and the incidence of anal cancer in the UK?
Conclusion
The study found that single men have a significantly increased risk of anal cancer, while being unmarried appears to be protective for women.
Supporting Evidence
- Single men had an odds ratio of 2.2 for developing anal cancer compared to ever married men.
- Unmarried women had a protective odds ratio of 0.6 against anal cancer.
- The study used data from three cancer registries in the UK.
Takeaway
Being single might make men more likely to get anal cancer, but for women, being unmarried seems to help protect them from it.
Methodology

Potential Biases
There may be selection bias in the recording of marital status among men with anal cancer.
Limitations
The study is limited by the rarity of anal cancer and potential inaccuracies in marital status classification.
Participant Demographics
384 men and 462 women with anal cancer were included in the study.
