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.

q3 i? Center-based care hours were near-zero predictors of outcomes in early childhood, but from about age 4–4½ became increasingly positively related to cognitive/reading and math scores and negatively related to behavior scores. → Mollborn 2014

q3 · i? · associational · r3

Supplemental growth curve models interacted weekly center-care hours with age and age squared (Figure 3). The authors report that care hours "became increasingly strongly related to cognitive/reading and math scores" from about age 4–4½, with a parallel negative pattern for behavior scores.

"Starting about at age 4 to 4½, the amount of time spent in center-based child care (which includes preschool) became increasingly strongly related to cognitive/reading and math scores."
