Claims

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? All three studies examining the pregnancy stage found contextual factors at that time point significantly related to children's cognitive composite scores. → Molly Grant 2023 q2 i? Thirteen studies of economic resourcing in early childhood (newborn–preschool) found evidence of significant associations with educational and cognitive outcomes. → Molly Grant 2023 (2)

Theme two of the review covers 26 timing studies; in the pregnancy stage "all sources found contextual factors at this time point to be significant," with antenatal maternal mental health directly affecting childhood cognitive composite scores.

"A distinct pattern was observed in the pregnancy stage, where all sources found contextual factors at this time point to be significant ( n = 3; Barker et al., 2013; Evans et al., 2012; Urizar & Muñoz, 2021)."

Among timing studies, 13 examining economic resourcing in the newborn–preschool years "found some evidence for this early life stage as having a significant association with both educational and cognitive outcomes," e.g., early poverty predicting middle-childhood cognition.

"those which investigated the effects of economic resourcing in early childhood (newborn–preschool years; n = 13) found some evidence for this early life stage as having a significant association with both educational and cognitive outcomes"
