| Slippery Slopes: Survival Analysis and Regression Clouds (Kaplan-Meier, Correlation and Regression Analyses) |
||||
| Participant profile The workshop is for everybody who has come into contact with the statistical plotting techniques of correlation/regression and Kaplan-Meier survival analyses and who wants to know more about what they mean. Ideally you should have encountered such plots in the context of clinical trials. Because some minimal statistical understanding is needed and terms like ‘median’, ‘mean’, ‘confidence interval’, ‘risk’ , and ‘p-value’ should not terrify you, you should have completed the EPDP foundation statistics workshop, ‘Using Statistics in Medical Writing’. Objective The objective is to acquire a basic understanding of correlation/regression and Kaplan-Meier analyses and to be able to interpret the resulting graphs. Content The workshop will try to give the participant an understanding of correlation and regression analyses and the analysis of survival in the context of clinical trials. We will learn the basics of regression analyses such as the difference between r, p and the 95% CI for a correlation followed by interpreting different Kaplan-Meier graphs and the different elements of reporting Kaplan-Meier analyses. The appropriate graphical and tabular presentation of these analyses will be discussed. There will be a few group exercises during the course. We will be touching on all essential elements of these analyses, pre-requisites, basic definitions, graphical and tabular presentation, but always the focus will be on the interpretation.
