Values are expressed as the mean of the 3 readers. GRI is interpreted as follows: Excellent: > 1.00 or < −1.00, good: ± 0.80–0.99, moderate: ± 0.50–0.79, poor: ± 0.00–0.49.

↵* Not possible to calculate owing to zero variance in scores in the placebo group. PsAMRIS: Psoriatic Arthritis MRI Score; MTP: metatarsophalangeal, IP: interphalangeal; MRI: magnetic resonance imaging; MCP: metacarpophalangeal; PIP: proximal interphalangeal; DIP: distal interphalangeal.
