Note: Linear regression models adjusted for age, gender and body mass index. R 2 adjusted <0.1 is not coloured. R 2 adjusted > = 0.1 and <0.2. R 2 adjusted > = 0.2 and <0.3.
Abbreviations: DIP, distal interphalangeal joint; DRUJ, dorsal radio‐ulnar joint; PDS, polysymptomatic distress scale; PPT, Pressure pain threshold (lower values reflect greater pain sensitization); SSS, symptom severity score; tib ant, tibialis anterior muscle; WSP, widespread pain. All were statistically insignificant after corrections.
