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? Parent explanation utterances at 42 months marginally predict PPVT scores at 54 months after controlling for parent education, prior PPVT, and word tokens. → Rowe Meredith L 2012

Regression analysis predicting PPVT at 54 months. "Parents’ use of explanations was also marginally related to later vocabulary skill (with narrative utterances and quantity of talk controlled)" in this diverse SES sample.
