HYPER-FOCUSED V3
We reviewed the live sessions from the 2024 and 2025 cohorts, plus Winter 2026, topic by topic. We kept the clearest explanations, strongest examples, and most current teaching, removed unnecessary repetition, and rebuilt the material into one focused pathway. The result is our most comprehensive and up-to-date version of Basics of Clinical Research Methods in Egypt to date.

Sample Size Calculation is Part 3 of the five-part Negida Research Skills Curriculum. Each course builds a different core research skill, and together they are designed to give medical students and doctors the foundational curriculum needed to start working in research with a clear structure rather than disconnected pieces of information.
