Internal study does mot have access to people who left because of unknown mental health treatment. They would had no way to evaluate them.

There is no reason to make imaginary issues of studies just to defend companies.

My point is if the people in the study were not randomly selected, there are any number of confounding factors that could influence why their anxiety changed.

Why are you so scared of people defending companies? Why can't your arguments stand on their own?
