The number of intact or non-intact images for each target joint is shown. For erosion, “Wrist” represents the navicular, the lunate, the radius, and the ulna; for JSN, “Wrist” represents the multangular-navicular, the capitate-navicular-lunate, and the radiocarpal joint
PIP proximal interphalangeal, IP interphalangeal, MCP metacarpophalangeal, CMC-M carpometacarpal joint of the thumb and multangular, JSN joint space narrowing, CMC carpometacarpal
