Learning objectives:
  1. To understand the principle, assumptions, procedure, and limitations of commonly used biostatistics methods in emergency medicine research, such as C-statistics, multivariable logistic regression and survival analysis.
  2. To learn more advanced statistical methods such as propensity score matching, bootstrapping, K-means clustering
This workshop is designed for participants with experience in EM research. Each topic will start with a real-life example EM researchers likely encounter in their work, followed by solutions provided by academic biostatisticians. The theoretical basis and practical steps of each biostatistics method will be explained. There will be a 5-minute Q&A session at the end of each topic.
