Study design in clinical research in hepatology

This course provides a comprehensive introduction to the design of clinical studies, equipping learners with the methodological foundations needed to critically evaluate and conduct high-quality research in liver disease. Through expert-led video lectures and practical examples, you will explore the strengths, limitations, and appropriate applications of the main study designs used in clinical hepatology research.

 

The course covers prospective and retrospective observational studies, randomized controlled trials, systematic reviews and meta-analyses, as well as emerging and innovative study designs increasingly used in modern clinical research. Special attention is given to biomarker and diagnostic studies, including principles of validation, clinical utility, and interpretation. Emphasis is placed on study selection, methodological rigor, bias reduction, and the translation of research findings into clinical practice.
