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? One-way ANOVA across digital-use tertiles showed main effects for EF composite (F(2, 365) = 14.87, p < .001, ηp² = 0.08) and cognitive reappraisal (F(2, 365) = 11.23, p < .001, ηp² = 0.06), with the high-use group lower than both other groups, which did not differ. → Shi Guochun 2026

Group comparisons stratifying the 368 adolescents into low, moderate, and high tertiles of objectively tracked screen time. Post-hoc Bonferroni tests showed "the high-use group scored significantly lower than both moderate and low-use groups on EF and reappraisal, whereas moderate and low groups did not differ".

"One-way ANOVA revealed significant main effects for both the EF composite (F(2, 365) = 14.87, p < .001, ηp² = 0.08) and cognitive reappraisal (F(2, 365) = 11.23, p < .001, ηp² = 0.06)"
