Demographic characteristics, age and baseline values (mean ± SE, ** p < 0.003, p < 0.0001), gender and race (W = white, AA = African American) and the stroke side (R/L = right/left), BP = mean blood pressure, BFV = mean blood flow velocity in the right (MCAR) and left (MCAL) middle cerebral artery, EtCO₂ = end tidal carbon dioxide
