Figure 1

Plot of differences against averages of simultaneous measurements of femoral and radial mean arterial blood pressures. The solid line represents bias (the mean difference between simultaneous measurements). Dotted lines show 95% limits of agreement (bias ± 1.96 standard deviation). The small bias (mean difference between simultaneous measurements) and the narrow 95% limits of agreement suggest the interchangeability of both measurements.
