The original version of this Article contained an error in Fig. 7, where it was truncated so that part (1) of Fig. 7 was not published. The incorrect Fig. 7 along with its caption is provided below.
Three-dimensional response surface (SBP, GT of LTM, GT of STM), correlation diagram of SBP-e SBP, error analysis diagram (137 subjects, 225 cases). The three-dimensional response surface is created by curve-fitting using the least squares method. The characteristics of the surface are indicated with a quartic polynomial, and using this quartic polynomial enabled us to estimate SBP. On the three-dimensional response surface (1), the dispersion of blood pressure is large between normotension and high normotension. On the correlation diagram of SBP-e SBP (2) and error analysis diagram (3), the dispersion up to high blood pressure is large. It is known that the heartbeat 1/f fluctuation contributes to the stabilization of blood pressure. Accordingly, this means that there is little 1/f fluctuation in this range. From the correlation diagrams of Mean-SD in Fig. 1 and in Fig. 2, it indicated that the dispersion of heartbeat rhythms was large in the 225 cases. It is assumed that the expanse of the dispersion of SBP between 110 and 140 mmHg was due that the 1/f fluctuation of heartbeat from nervous control was reflected on GTs.
