Hand radiographic features of KBD and the four criteria used for diagnosing adult KBD. Right hand of a 55 year old female KBD study participant with brachydactyly (A) and her right hand radiograph (B). The four hand radiographic features used for diagnosing adult KBD are marked with colored arrows: articular surface depression with sclerosis (yellow); “carpal crowding” (red); subchondral bone deformity in the proximal end of the phalanx (blue); and bony enlargement (between white arrows) with deformity of the distal end of phalanx (green).

3. Fig. 2
Frequency of radiographic OA features of the joints of digit 1 (thumb) of the hand. The left panels represent the frequency of OST ≥ 1 (A), JSN ≥ 1 (B) and KL grade ≥ 2 (C) in the three joints of digit 1 (thumb). The right panels represent the severely affected subgroups with OST = 3 (D), JSN = 3 (E) and KL grade = 4 (F). IP, Interphalangeal joint; MCP, metacarpal-phalangeal joint; CMC, carpometacapal joint; All statistical analyses were adjusted for gender, age and BMI. +, P value < 0.05; ++, P value < 0.01; +++, P value < 0.001.

4. Fig. 3
Frequency of radiographic features of the joints of digits 2–5 of the hand. The left panels represent the frequency of any OST ≥ 1 (A), any JSN ≥ 1 (B) and any KL grade ≥ 2 (C) in three joint groups: DIPs, PIPs and MCPs of the four fingers (digits 2–5). The right panels represent the severely affected subgroups with any OST = 3 (D), any JSN = 3 (E) and any KL grade = 4 (F). DIPs, distal interphalangeal joints; PIPs, proximal interphalangeal joints; MCPs, metacarpal-phalangeal joints. All statistical analyses were adjusted for gender, age and BMI. +, P value < 0.05; ++, P value < 0.01; +++, P value < 0.001.

5. Supplementary Fig. 1
Frequency of radiographic features of individual joints of digits 2–5 of the hand. The left panels represent the frequency of any OST ≥ 1 (A), any JSN ≥ 1 (B) and any KL grade ≥ 2 (C) in individual joints of the four fingers (digits 2–5). The right panels represent the severely affected subgroups with OST = 3 (D), JSN = 3 (E) and KL grade = 4 (F). DIP, distal interphalangeal joint; PIP, proximal interphalangeal joint; MCP, metacarpal-phalangeal joint; D2, D3, D4 and D5 refers to digits 2 through 5. All statistical analyses were adjusted for gender, age and body mass index (BMI). +, P value < 0.05; ++, P value < 0.01; +++, P value < 0.001.
