Cardiac function and arterial stiffness related measures were compared between ART naïve (Gp1) and virologically suppressed on-ART (Gp2) patients and healthy controls (Gp3). Measures of cardiac functions include A), estimated cardiac ejection time; B), estimated stroke volume; C), estimated stroke volume index; D), estimated cardiac output and E), estimated cardiac index. F-H: Measures of arterial stiffness include F), systemic vascular resistance, G), large artery elasticity index and H), small artery elasticity index. Data between groups are compared using Wilcoxon rank-sum test; a p value of <0.05 was considered significant. *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001.
