Fig. 1. Peripheral (radial) and central (aortic) systolic pressure response during the black tea and the green tea study. Each line represents response defined as net tea or caffeine effect minus hot water effect at each time point. P values refer to the response of tea or caffeine compared to hot water during the whole study duration. Error bars: SEM.
