The first four rows give mean values for heart rate data [beats/s] during sitting, supine, standing, and tilt positions. The next two rows gives the maximum change observed between baseline (sitting or supine) and standing or tilt, respectively. The last six rows provide the same measures for the mean blood pressure data
