#### About the webinar

In this free webinar, we will examine the important design considerations for analyzing recurring events and counts.

Recurring events are common in clinical trials (e.g. COPD exacerbations, MS relapses) but have often been analysed using survival models or other approximations. But these simple approaches fail to use every event.

This has led to increasing interest in recurring event and count models and how these allow us to analyse all recurring events or counts and thus provide additional insight and power.

> In this webinar, we will cover the different options for the analysis of recurring events and counts, the sample size calculations available for this area including adjustments for unequal follow-up and dropout, and extensions of the group sequential design framework to the recurring event endpoint.

**

#### In this free webinar you will learn about: 

- What are recurring events and how should we analyse them
- The design issues, models and pitfalls in recurring events
- Sample size determination for recurring events and counts
- Group sequential design for recurring events

**

#### Duration - 60 minutes
