Figure 1 Changes in Brachial Artery Flow-Mediated Dilation From Baseline to Week 24

Thick bars = medians; box edges = 25th and 75th percentiles; error bars = 95% confidence intervals. EFV = efavirenz; FMD = flow-mediated dilation; LPV/r = lopinavir/ritonavir; NNRTI = non-nucleoside reverse transcriptase inhibitor; NRTI = nucleoside reverse transcriptase inhibitor; PI = protease inhibitor. *p 0.005, #p = 0.015 within arm, compared with baseline (between groups, p = 0.828).
