- Mrs. Anderson, a 45-year-old woman with a history of chronic back pain, has been taking X as prescribed by her rheumatologist for the past eight months. During a routine check-up, her liver function tests revealed significantly elevated liver enzymes. She has not experienced any noticeable symptoms but is now being closely monitored for potential liver-related issues. 2. Propose a pharmacoepidemiological study design to confirm or refute the signal of hepatotoxicity associated with X. Consider factors such as study population, exposure definition, and outcome measures. Discuss the strengths and limitations of your chosen study design? Outline the methods and data sources that could be used to collect information on hepatotoxicity in patients using X.? Discuss how the findings of the study could have regulatory implications.
