Systematic reviews and meta-analyses are often considered among the highest levels of clinical evidence—but only when they are performed using rigorous, transparent methods. In this episode of This Is Why with Dr. Busti, you'll learn the essential steps involved in conducting and critically evaluating a systematic review and meta-analysis, from developing a focused clinical question through assessing risk of bias, heterogeneity, and pooled results.

Whether you're conducting research or interpreting published medical literature, understanding the systematic review process can help you evaluate the validity of its conclusions. Dr. Busti explains why each step matters and how understanding the methodology supports evidence-based clinical decision making.

Topics Covered:
- Systematic review and meta-analysis methodology
