3. Fig 2
RN plotted as a function of CSSA score. Circles represent the average post-incision RN values after start of skin incision in the 55 patients, whose parameters were used in the development of RN. Values of an additional 10 patients, not used in development of RN, are marked with crosses.

4. Fig 3
Behaviour of RN differentiates patients with big incision from the others (a) (P=0.04); movers from non-movers (b) (P=0.02); and low, intermediate, or high effect site concentrations of remifentanil from each other (c) (P= ). Values on the horizontal axis indicate time relative to the moment of skin incision. The curves show the mean RN. The length of the error bars indicates se. Curves are calculated over all cases (n=55) for (b) and for non-movers only (n=50) for (a) and (c).

Schematic presentation of the algorithm to calculate RN. All three modules use a multivariate equation. The outputs of these three equations are combined linearly to obtain the RN value. PPGV=pulse plethysmography variability.
