Bland and Altman who introduced this measure, thought that looking at the range where an individual test score would fall 95% of the time may be more relevant than comparing test and retest. The dimension of the test values (calibration or scaling across ergometers and analysers) needs to be accounted for when comparing the same population across different tests [5], as differences in scales will affect SEM size.
