3. What are the key ethical considerations in clinical research?

   • Answer: Key ethical considerations include informed consent, minimizing risks to participants, maintaining confidentiality, data integrity, and equitable selection of participants.

4. Describe your experience with data management in clinical trials.

   • Answer: [Insert detailed answer based on personal experience, including specific software, data cleaning techniques, and experience with databases like REDCap or similar.]

5. How do you ensure data integrity in a clinical trial?

   • Answer: Data integrity is ensured through careful data collection methods, regular data validation and cleaning, proper documentation procedures, audit trails, and adherence to GCP guidelines.

6. What is your experience with statistical analysis in clinical research?

   • Answer: [Insert detailed answer based on personal experience, including specific statistical software like SAS, R, or SPSS, and experience with different statistical tests like t-tests, ANOVA, regression analysis etc.]

17. What is per-protocol analysis? How does it differ from ITT analysis?

    • Answer: Per-protocol analysis includes only participants who completed the study according to the protocol. It may provide a more optimistic estimate of treatment effects but may be subject to bias.

    • Answer: [Insert detailed answer based on personal experience, including CRF design, data entry, and data validation.]
