Figure 2. Adjusted cerebral vasoreactivity by type of antiretroviral therapy (ART)^a.

Use of lopinavir/ritonavir was associated with lower mean cerebral vasoreactivity (measured with breath holding index) compared with use of efavirenz, independent of the duration of HIV infection or use of antiretroviral therapy.

^aAdjusted for age, statin use, coronary heart disease/myocardial infarction, duration of HIV infection and duration of antiretroviral therapy use.
