Tables, Listings, Graphs

Generation of Tables, Listings and Graphs

The data are collected in clinical trials are tabulated in a very formal way. The required statistical activites are summarised in the Statistical Analysis Plan (SAP), while the associated Table Sheel will say the exact format of the outputs. Basically there are three types of the outputs:

  • Tables translate the majority of the obtained information. Tables generally represent several dimensions (frequently more than two) amd are capable to show information in a structured manner (e.g. mean values of laboratory data before and after treatment).
  • Graphs are generally introduced to support the interpretation of the primary, some secondary or safety results. A good example of survival type analyses, where a graph with Kaplan-Meier estimation really says more than 100 words.
  • Listings provide transparency: they make possible a potential recheck of the results and to identifdy and explain some data issues.
