CRP and rheumatoid arthritis: Change in sedentary time was not significantly linked to change in DAS-28 (β = 0.24) and pain (β = 0.26), change in standing time was not significantly related to change in DAS-28 (β = − 0.24), and change in stepping time was not significantly associated with change in any RA outcomes (DAS-28, β = − 0.11; CRP, β = − 0.34; pain, β = − 0.07; fatigue, β = − 0.05).
