From: Bench-to-bedside review: The importance of the precision of the reference technique in method comparison studies – with specific reference to the measurement of cardiac output

Figure 4

Precision of the reference technique for n averaged measurements and the corresponding percentage error (PE) from the Bland-Altman plot for a fixed level of precision of the studied technique (29%). The PE can change simply by using a more or less precise reference technique, even when the precision of the studied technique is not changed. This may lead to the acceptance of a studied technique even though its performance in terms of precision stays the same. CE, coefficient of error.
