Figure 2: Bias plot comparing cardiac output measurements from continuous cardiac output PAC and EDM in women (left) and men (right). The mean of the two methods can be seen on the X-axis. The difference between the two methods can be seen on the Y-axis. The shaded area indicates the 95% confi dence interval (CI). Note the signifi cantly greater negative measurement bias noted in women - Table 1 for exact values.
