Immunodiagnostic Significance of Anti-RA33 Autoantibodies in Saudi Patients with Rheumatoid Arthritis

Table 6

Linear regression analysis of the diagnostic markers of RA with CRP and RF values.

Variables	C-reactive protein			Rheumatoid factor
	Constant	-coefficient	value	-coefficient	value
Anti-CCP	328.3	−0.192	0.220	0.240	0.128
Anti-RA33	−8.47	0.576	<0.00	0.024	0.857

Linear regression shows significant correlation between anti-RA33 values and CRP changes.
No notable correlation was observed between anti-CCP and the CRP or RF values.
