Differences in vascular parameters between SLE patients with and without hypertension

	CTL (n = 0)	SLE - hypertension (n = 21)	SLE + hypertension (n = 9)
SAE, ml/mmHg × 100	8.1 ± 2.6	6.4 ± 2.1*	6.4 ± 4.0
AF, AU	1.9 ± 0.4	2.1 ± 0.5*	2.2 ± 0.6
IMT, mm
Mean Maximum	0.72 (0.69 to 0.87)	0.70 (0.68 to 0.76)	0.73 (0.60 to 0.98)
Mean	0.64 (0.59 to 0.70)	0.61 (0.58 to 0.65)	0.62 (0.55 to 0.81)
VCAM-1, ng/ml	371 ± 101	534 ± 159**	578 ± 182**
vWf, %	67 (46 to 88)	123 (89 to 189)**	156 (83 to 397)**
TM, ng/ml	1.6 (1.2 to 1.7)	1.8 (1.4 to 2.6)	1.3 (0.6 to 1.8)

Unless stated otherwise, data are expressed as mean ± standard deviation when normally distributed and as median (interquartile range) when non-normally distributed. AF, autofluorescence; AU, arbitrary units; CTL, healthy controls; MT, intima media thickness; SAE, small artery elasticity; SLE, SLE patients; TM, thrombomodulin; VCAM-1, vascular cell adhesion molecule-1; vWf, von Willebrand factor. Patients versus controls: * P ≤ 0.05, ** P ≤ 0.01. There were no significant differences between SLE patients without hypertension and SLE patients with hypertension.
