Figure 1. Pulse Wave Velocity (PWV) is high in SLE patients and correlates with systolic blood pressure.

Figure 1

(A) Pulse wave velocity (PWV) are higher in SLE patients (SLE, n = 41, right) as compared to controls (CTL, n = 35, left) and (B) correlated with internal carotid wall thickness (ICWT). (C) SLE patients and controls were stratified according to systolic blood pressure quartiles (SBP <119; 120–126, >127–135, >137 mmHg). Two-ways ANOVA showed a significant independent interaction of SBP and group (SLE, CTL) on PWV. (D) PWV correlated with systolic blood pressure (SBP) in SLE subjects with (white circles) and without (black circles) high systolic blood pressure. Plain and dashed lines represented linear regression in SLE subjects with and without high systolic blood pressure (SBP), respectively. p was calculated after age adjustment. m/s refers to meter per second; mm, to millimeter; r, to linear correlation coefficient
