Are there specific outcome measures of interest for this PFA?

The emphasis in choosing an outcome measure should reflect an important clinical dilemma faced by patients in deciding between two efficacious options during the course of treatment.  While short-term or immediate relief should be measured, longer term follow up should be a minimum of six months. Life expectancy for potential participants should be projected to be at least six months following study enrollment.

Caregiver outcomes are also of interest in cases where appropriate, especially in pediatric or adolescent patients.
