The writing they used in abstract is confusing, the full quote: “Exposure therapy showed large effects relative to waitlist and treatment-as-usual, a small effect relative to non-trauma-focused comparators and a negligible effect relative to other trauma-focused treatments or medication. At follow-up most effects sizes were stable, except for a medium effect favoring exposure over medication.”

They mean exposure is much better than doing nothing, a bit better than “non-trauma-focused comparators“ and on par or negligibly better then the most effective approaches, for example, exposure is often used as a part of a larger therapy like trauma focused CBT
