Estimated relationship between PASDAS/Pain VAS (a) and ScoreMDA/SF-36v2 PCS (b). Data from OPAL Broaden (N = 422). SF-36v2 PCS: norm-based scores were used (a score of 50 representing the mean for the general population, with higher scores indicating less impairment); ScoreMDA: continuous MDA with values from 0 to 7 (0–4, no MDA; 5–7, MDA). Arrows indicate the direction of improvement. MDA, minimal disease activity; Pain VAS, Patient’s Assessment of Arthritis Pain visual analog scale; PASDAS, Psoriatic Arthritis Disease Activity Score; PCS, Physical Component Summary; SF-36v2, Short Form-36 Health Survey Version 2, acute
