NDT (1998) 13: 739744
In a recent discussion referring to our measurements of access resistance in dialysis patients the authors identified a mistake in the calculation of peripheral resistance units (PRU). Data were divided by 0.6 instead of multiplied because of a mistake in placing the parentheses in the Microsoft Excel spreadsheets. Thus, the PRU published in NDT (1998) 13: 739744 have to be multiplied by a constant factor of 0.36 to obtain the correct absolute values for total peripheral resistance (TPR), systemic vascular resistance (SVR) and access resistance (AR) (Abstract, Results, Table 1, Figure 4a
and b
). The analysis of the changes in TPR (
TPR%), SVR (
SVR%) and AR (
AR%), and the conclusion that access resistance remained stable during the observation phase, are not affected by this mistake. The authors apologize for this error and for any problems this mistake may have caused. The correct versions of Table 1
and Figure 4a
and b
are shown below.
