The pathway analysis will only report on people that have at least 1 event cohort occurrence within the target cohort’s start and end date. So you could have some people that are in your cohort, but did not have ANY of the cohort events you specified in your pathway analysis.
Therefore, the ‘target cohort count’ = number of people in your cohort, and ‘persons with pathways count’ = number of people from your target cohort that had at least 1 path.
In case you are wondering ‘why?’: it is possible that you could have a large cohort where only 5% of people have at least 1 path. If we were to represent the 95% in the visualization, you’d have this 95% hole in the graph, with 5% of the remainign space dedicated to the actual data contained in the pathway analysis. We decided that showing that hole is not useful, and instead annotated the result with ‘People in Cohort vs. People in Pathway Results’.
