The lecturer explains number needed to treat (NNT) and number needed to harm (NNH), including calculations and clinical relevance. Sensitivity and specificity of diagnostic tests are discussed, emphasizing their importance in clinical decision-making. Various study designs—case-control, cohort, randomized controlled trials, and adaptive designs—are reviewed, noting their strengths and challenges, with adaptive designs gaining prominence especially during COVID-19. The talk concludes with a Q&A stressing the importance of clinician involvement in trial design to ensure relevant research questions that impact patient care. Overall, this session aims to empower clinicians to critically appraise research and apply evidence appropriately.
