Extrapolation to paediatrics

Interview with Andrew Thomson

What is extrapolation?
How can we use extrapolation in paediatrics?
What are the main challenges?

Paediatric research always comes with challenges, and understanding paediatric submission is vital. There’s always a lack of treatment in this area. In this episode, you’ll understand what you can do to get evidence through extrapolation for the children population.

Stay tuned while Andrew and I talk about the following:

  • What is extrapolation?
  • What are source and target populations?
  • The guidance states: “Where possible, quantitative methods should be used for the collation of available data and the investigation of potential modifiers of the treatment effect”. How could such quantitative methods look like?
  • What are the major challenges?
