Table 2. Association of gender and age with sonographic measurements.

A. Sonographic measures				RA	Female	Male	p-value
	1-cIMT (mm)			0.645 (0.117)	0.627 (0.15)	0.678 (0.129)	0.005
	2-Plaque presence (%, n)			43.5 (93)	36.2 (50)	56.6 (43)	0.004
B. cIMT			Coefficients			R2 (%)	p-value
			β	SE	95% CI
	Adjusted model					37	0.0001
		Gender	0.059	0.017	0.025–0.093	3.8	0.001
		Age	0.0048	0.00067	0.0035–0.0061	16	0.0001

(A1). Mean cIMT values in overall RA patients and divided by gender. ANOVA statistics for gender association with cIMT. (A2). Percentage of plaque presence in overall RA population and divided by gender. Chi-squared statistics for gender association with plaque presence. (B). Adjusted β linear regression estimates of the effect of age and male gender on cIMT applied to the overall population. The model is adjusted for disease duration, body mass index, ischaemic heart disease, ictus, peripheral artery disease, creatinine, hypertension, dyslipidaemia, type 2 diabetes mellitus, disease-modifying antirheumatic drugs, biological agents, corticosteroids, and non-steroidal anti-inflammatory drugs.
