Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

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

q2 i? Preschool attendees demonstrated higher externalizing behavior upon kindergarten entry (E.S. = 0.18 SDs) that persisted at reduced levels through the end of fifth grade (E.S. = 0.05–0.16 SDs), relative to matched informal-care peers. → Ansari 2018

q2 · i? · associational · r2

In the same matched-sample path models of the ECLS-K 1998 cohort, teacher-reported externalizing behavior (adapted Social Rating Scale) was worse for preschool attendees at kindergarten entry with a printed effect size of E.S. = 0.18 SDs, persisting at reduced levels through fifth grade (E.S. = 0.05–0.16 SDs).

"preschool attendees were found to demonstrate higher levels of externalizing behavior upon kindergarten entry (E.S. = 0.18 SDs), which persisted at reduced levels through the end of fifth grade (E.S. = 0.05–0.16 SDs)."
