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.

q3 i? For the 3-year-old cohort at the end of the intervention year, statistically significant positive effects were confirmed on one social-emotional subscale and on two comparisons based on subgroups formed by mothers' race/ethnicity. → What Works Clearinghouse 2015
