Correct detection rates for intact (SHS = 0) joints, non-intact (SHS ≥ 1) joints, and the total for each target joint are shown. The numbers represent the correct detection/total cases (correct detection rates %). In erosion, “Wrist” represents the navicular, the lunate, the radius, and the ulna. In JSN, “Wrist” represents the multangular-navicular, the capitate-navicular-lunate, and the radiocarpal joint
