Ultrasound synovitis and tenosynovitis were graded semi\u2010quantitatively (0\u20103) and dichotomously (0 or 1), respectively. The (a) power Doppler (PD), gray\u2010scale (GS) and combined (PD + GS) ultrasound (CUS) scores and (b) their positivity (score &gt; 0) were analyzed using a general linear repeated measures mixed model (a) assuming Gaussian errors and (b) with binary distribution and logit link, respectively.
