RE: [BIONT-DSE] Inclusion versus exclusion criteria

Alan,

My guess (and some based from my own experience), is that it supports the way a lot of non-technical clinicians like to organize the process: 1) what I want, 2) what I must avoid.

I beleive you are right that exlcusion is simply an explicit set of OR-ed negations. An interesting thing to find out would be whether there are any exclusions forms that are AND-ed negations-- in which a simple list of exclusion criteria would be insufficient.

Subject: [BIONT-DSE] Inclusion versus exclusion criteria
 

Something that I remain confused about is why there are two  
categories of criteria, when, on the face of it, the negation of an  
exclusion criterion is an inclusion criterion.

So I'm wondering, is there something between the lines? Is there  
something other than the negation? Perhaps kind of criteria, or  
lesser necessity, or derivation from different sources? Open versus  
closed world? Otherwise, from a technical point of view can we just  
consider these the the same sort of thing, with a flag indicating how  
they should be shown in a hypothetical user interface?
