Hypothesis
Is there a relationship between coffee and tea consumption and the risk of pancreas cancer?
Conclusion
The study found no evidence of a positive relationship between pancreas cancer and coffee consumption, but a significant positive relationship with tea consumption.
Supporting Evidence
- There were 216 cases of pancreas cancer and 432 controls in the study.
- More women than men drank coffee daily, but nearly all drank tea daily.
- The risk of pancreas cancer for daily coffee drinkers was 0.9 compared to non-drinkers.
- There was a significant positive relationship between tea consumption and pancreas cancer.
- Heavy tea drinkers were more often smokers.
Takeaway
Drinking coffee doesn't seem to increase the risk of pancreas cancer, but drinking a lot of tea might.
Methodology
A case-control study analyzing data from individuals with pancreas cancer and matched controls regarding their coffee and tea consumption.
Potential Biases
