This study investigates the use of a particular method, referred to as Indiana staging, which is a way to assess the progression of a specific condition. The purpose of using Indiana staging is to better understand how the condition develops over time and to evaluate its effectiveness in providing accurate assessments.

Participants will undergo specific procedures related to Indiana staging. The procedures will involve assessments and evaluations that are designed to gather detailed information about the condition's progression.
