# PHQ Rank PHQ Rank is a numeric value on a logarithmic scale between 0 and 100 to represent the impact of the event. The larger the value of the rank, the higher the impact of the event. * PHQ Rank is independent of the event’s location. * PHQ Rank for non-attended categories and unscheduled categories are further explained under each category. * PHQ Rank is comparable between attended events in terms of the event’s size or impact. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
