Didactics-Systematic Reviews and Metanalysis

Video Transcription

Video Summary

In this lecture, Nury Agustí explains the importance of systematic reviews and meta-analysis in medical research. Systematic reviews involve a structured approach to summarizing and evaluating existing research evidence on a specific topic, minimizing bias and providing reliable results. Meta-analysis takes systematic reviews further by performing statistical analysis on data from individual studies included in the review. These reviews and analyses play a crucial role in guiding medical decisions, shaping evidence-based guidelines, empowering doctor-patient discussions, and identifying research priorities. Agustí provides a 10-step guide on how to conduct a systematic review and meta-analysis, starting with defining the focus and framing the research question using the PCOP acronym (Population, Intervention, Comparison, Outcome, and Time). Other steps include developing a search strategy, executing the search, screening and data extraction, assessing the risk of bias in studies, performing meta-analysis if appropriate, and writing and reporting the findings following standardized guidelines such as Prisma and AMPster. Collaboration, adherence to protocols, and attention to detail are emphasized throughout the process.
