Effect of an additional short-circuited pair of electrodes on bipolar and tripolar configurations. The IRs are presented in box plots where the central mark represents the median value; the edges of the box are the 25th and 75th percentiles; the whiskers give the range of data values; laterally pointing triangles represent average values. An asterisk is used to show the statistically significant IR (p < 0.05).
