This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

Meta-analytic moderator analysis across the 24 included studies. The article reports that interventions "delivered during late adolescence (15–18)" had the largest effects; no effect size for this moderator contrast is printed in the available text.
