Association between ambient temperature and (A.) resting blood flow velocity (BFV), (B.) resting cerebrovascular resistance (CVR), (C.) resting mean arterial pressure (MAP), (D.) and cerebral varoreactivity (Cerebral VR).

<p>The <i>y</i>-axis denotes the % change (and 95% confidence interval) in each outcome per 10°C increase in temperature, adjusted for age, sex, race, smoking, hypertension, diabetes, BMI, visit number, day of week, season, and long-term time trends. The x-axis denotes the averaging period for ambient temperature (in days) prior to the TCD assessment.
