Resum	The Physician Global Assessment (PGA) is a clinician-rated, single-item measure of overall systemic lupus erythematosus (SLE) disease activity on a visual analogue scale (0–10). Used alongside structured indices like SLEDAI, PGA captures the clinician's integrated judgment of SLE severity, synthesising clinical examination, serology, imaging, and organ-specific findings into a holistic activity score. PGA is simple, practical, and widely used in SLE research and clinical practice as a complementary measure that reflects experienced clinician assessment of disease state.	The BASDAI is a patient-reported outcome measure of disease activity in ankylosing spondylitis (AS), a chronic inflammatory arthropathy affecting the spine and axial skeleton. Introduced by Garrett et al. in 1994, BASDAI uses six simple patient self-report items focused on the cardinal symptoms of AS: fatigue, spinal pain, peripheral joint involvement, and morning stiffness. As a PRO measure, BASDAI is practical for routine monitoring, responsive to treatment, and strongly associated with clinical outcomes and spinal damage progression, making it a cornerstone outcome in AS management and clinical trials.
