Statistical tools can not only cut through the noise in large pharmacovigilance databases. They can also help identify more clinically meaningful patterns in the data. Uppsala Monitoring Centre’s Jim Barrett and Joe Mitchell explain how vigiGroup, a novel clustering algorithm, can bring value to signal detection.

Tune in to find out:

• What the limits of traditional disproportionality analysis are
• How clustering algorithms can improve current signal detection practices
• How vigiGroup has helped monitor the safety of COVID-19 vaccines so far

Want to know more?

• By applying vigiGroup to COVID-19 vaccine reports in VigiBase, our Research team was able to identify a number of potential safety signals. Find out more in this poster or in this presentation. 
• Details on how the vigiGroup method was developed and tested can be found in the original publication in Artificial Intelligence in Medicine.
• Appendicitis was one of the possible safety signals for the COVID-19 vaccines identified with vigiGroup.
