Hypothesis
Does the use of combination oral contraceptives reduce the risk of epithelial ovarian cancer?
Conclusion
The study found that women who used oral contraceptives had a significantly lower risk of developing epithelial ovarian cancer.
Supporting Evidence
- 18 (9%) of women with ovarian cancer used oral contraceptives compared to 59 (14%) of controls.
- The relative risk estimate for ever use of oral contraceptives was 0.6.
- The risk of ovarian cancer decreased with increasing duration of oral contraceptive use.
Takeaway
Using birth control pills can help lower the chances of getting a certain type of ovarian cancer.
Methodology
A case-control study was conducted with 209 women with ovarian cancer and 418 age-matched controls.
Potential Biases
There is a low risk of bias due to the lack of widespread knowledge about the study's hypothesis among participants.
Limitations
The study may not account for all potential confounding factors, and the sample is limited to a specific population in Milan.
Participant Demographics
Women below the age of 60, with 209 cases of ovarian cancer and 418 controls with unrelated conditions.
