Measurable differences between sequential and parallel diagnostic decision processes for determining XXXX subtype: a representation of interacting pathologies.

@entity1 @entity64 @entity1503 @entity715 @entity385
@entity64 diagnosis depends on causal subtype. The accepted classification procedure is a succession of diagnostic tests administered in an order based on prior reported frequencies of the subtypes. The first positive test result completely determines diagnosis. An alternative approach tests multiple concomitant diagnostic hypotheses in parallel. This method permits multiple simultaneous pathologies in the @entity1 . These two diagnostic procedures can be compared by novel numeric criteria presented here. @entity715 , a type of @entity385 , results from interaction between endothelium, @entity1503 . We tested for @entity385 on thirty @entity1 using both methods. For each @entity1 the procedure produced an assessment of severity as an ordered set of three numbers in the interval [0, 1]. We measured the difference in diagnosis between the sequential and parallel diagnostic algorithms. The computations reveal systematic differences: The sequential procedure tends to under-diagnose and excludes any measure of interaction between pathologic elements.
