The parameters for inclusion do not say that the girls must ALREADY be seeking termination. This is the actual link to the study. Nor does it say that all of the inclusion criteria must apply.
The very first "Inclusion Criteria" is that the subject is "Requesting pregnancy termination."
And, by definition, all inclusion criteria must apply. That's how clinical research studies work - the list of inclusion criteria is a list of essential criteria that all study participants must have. So the page does not need to explicitly say that all inclusion criteria must apply, because that's what "inclusion criteria" means.
