Question 1: Question and study design

1. Research Question: How can cachexia be prevented in cancer patients receiving aggressive protocols involving radiation and chemotherapy?
2. Study Design: Choose three different types of study designs you could use to examine the exposure-outcome relationship. Be sure to include whether your chosen studies are observational or experimental.

Question 2: Study Comparisons

1. Population Selection: Identify the method(s) used by each study to assign participants into the study.
2. Timing Approach: Describe the timing approach you would use for each study.
3. Measures of Association: List the measures of association that will be used by each study. Be sure to include a brief description of how you will interpret these measures for the exposure-outcome relationship.
4. Confounding: Determine a third variable that could be a confounder for your exposure disease relationship. Be sure to include one method to control for confounding.
5. Bias: Identify a potential source of bias in the design for your research question. Be sure to identify at least one way to mitigate this potential bias.

Question 3: Conclusion

Conclusion: Determine which type of study design is best suited to answer your research question. Explain your rationale for this conclusion.
