Table 3

Multiple linear regression analysis of associations between SAA concentration and laboratory as well as ECG parameters.

SAA/variables		value
CRP	0.44	<0.0001
WBC	0.318	<0.0001
QTc	−0.21	0.004

SAA: serum amyloid A; CRP: C-reactive protein; WBC: white blood cell count; QTc: corrected QT interval.
