Treatment Alternatives in iSGS (NoAAC PR-02 Study)

The study is aimed at answering the questions; (1) How well do the most commonly used treatments in iSGS work? and (2) What quality-of-life trade-offs are associated with each approach?

With the results of this trial, the investigators hope to provide information to iSGS patients: (1) Given my personal characteristics, conditions, and preferences, what should I expect will happen to me? and (2) What are my options, and what are the potential benefits and harms of these options?
