a Differences were evaluated with the Independent Samples t-test. Numbers per group differ because 15 patients have incomplete data on one or more GFI domains. Number of questions and score range per domain: Physical domain: 9 questions, score range 0–9; Cognitive domain: 1 question, score range 0–1; Social domain: 3 questions, score range 0–3, Psychological domain: 2 questions, score range 0–2.
