*Peripheral phenotypes: monoarthritis/oligoarthritis, polyarthritis, dactylitis, enthesitis, arthralgia.
†Peripheral Imaging only.
‡Did not specify polyarthritis.
§Number of joints not specified.
¶Noted no swelling but did not define further.
**Joint symptoms reported exclusively as arthralgia—no mention of arthritis.
††Ultrasound recorded synovial hypertrophy, enthesitis and tenosynovitis, but did not report enthesitis separately.
OA, osteoarthritis; pArthritis, peripheral arthritis; pSpA, peripheral spondyloarthritis; Rheum, rheumatologist; US, Ultrasound; Sx, symptomatic; aSx, asymptomatic
