We are using Atlas characterization.
The feature 27 called : Condition Group Era Any Time Prior groups conditions into some higher level categories.
Can the software author please explain how these categories are defined? Can we rely on them being “perfect” or “good enough” phenotypes (for a journal paper).
Atlas defines those as “27 Condition Group Era Any Time Prior One covariate per condition era rolled up to groups in the condition_era table overlapping with any time prior to index.”
Is the grouping based of MedDRA? Or some set of preferred set of SNOMED roll-up terms? Do the groups cover all of medicine or just sub-parts selected by software author?
Additionally, we would also need similar GROUP feature for procedures or other domains.
analysis 87 is Procedure Occurrence Any Time Prior. But no grouping is offered for procedures.
Similarly drug ingredient group.
Note that for the source we are working with, we can’t execute an R package. We can only do what Atlas offers out of the box and nothing more. So consider this context if replying.
