An excellent example of a Causal test is the “Comprehensive Analysis”. Selecting Causal ensures that only items that are related to causal chain issues are added to the hold tank.
An example of the 1X1 test is seen in the “Informational Scan”. It has many of the same challenges as the Comprehensive Analysis only instead of being set as a causal, it is set as a 1X1.
So, in the scenario that we used in the slide above, if 1X1 was selected, all 5 vertebra would be placed in the hold tank and not just the 1 that was a part of the causal chain.
