Summary: The TOST equivalence test indicates TempTraq® is not equivalent to Pulmonary Artery Catheter. The Bland-Altman test for agreement indicates TempTraq® is in agreement with Pulmonary Artery Catheter and there is an overall bias of .3 between the two measurement systems. There is no significant difference in the precision of the two methods. There is a significant difference in accuracy. The accuracy analysis confirms the significance of the bias observed in the Bland-Altman test. If the bias value of .3 is added to each TempTraq® measure a re-analysis indicates the two measures are equivalent, in agreement, and exhibit no significant difference in precision or accuracy.
