Introduction the VO2max conducted with direct and indirect measurement did not show a significant difference. A model should also specify how these entities are related to the attributes and how the characteristics relate. 'Direct measurement' refers to measuring exactly the thing that you are looking to measure, while 'indirect measurement' means that you're measuring something by measuring something else. However, due to the large spread of data around the regression line, such equations should not be employed to decide when to use direct electrodes instead of indirect electrodes in routine clinical laboratories.
