For Pearson correlation coefficients, higher values indicate a closer relationship. All P < 0.0001, except for the correlation between BSA and FFbH (P = 0.0002), pain and enthesitis (P = 0.0093) and FFbH and enthesitis (P = 0.0050).
a
Functional remission (FFbH ≥83%). FFbH is assessed on a scale of 0 (total loss of functional capacity) to 100 (maximal functional capacity). BSA: body surface area; FFbH: Funktionsfragebogen Hannover; MDA: minimal disease activity; PGA: patient global disease activity assessment; SJC: swollen joint count; TJC: tender joint count.
