Presentation Transcript

    1. Introduction to Basic Statistics for Clinical Research

    2. Learning the Language Concept of Sampling Variable types Categorical (qualitative; nominal) Ordinal Numerical (continuous; interval; ratio) Independent vs. Correlated Data Parametric vs. Non-parametric

    3. Learning the Language Study Design Sampling Strategy Analysis Types Discrete vs. Time-dependent (survival) Logistic vs Linear Regression Model Building Interactions

    4. Sample Size The number of subjects required in a study to achieve statistical significance, given a number of a priori assumptions.

    5. Power Considerations: The assumptions Control value or rate Effect size dependent on parameter of interest best to have pilot data Significance level (?) 1-tailed or 2-tailed testing Power (1-?) Confounders Non-compliance Cross-overs Drop Ins Drop Outs Lost to follow up
