BRAF and rheumatoid arthritis: Interestingly, BRAF‐MDQ global fatigue score positively correlated with BFI‐C global fatigue score in both RA patients (r = .669, p < .001) and healthy controls (r = .527, p < .001); meanwhile, Kendall's tau‐b test showed a high consistency between BRAF‐MDQ and BFI‐C global fatigue scores in RA patients (W = 0.759, p < .001) and healthy controls (W = 0.933, p < .001).
