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? Only adolescents in the high-exercise group (more than 4 h/week) differed significantly from lower-exercise groups on cognitive measures; low and moderate groups did not differ. → Reigal 2020

Evidence

Reigal, R. E., Hernández-Mendo, A., Juárez-Ruiz de Mier, R., and Morales-Sánchez, V. (2020). Physical Exercise and Fitness Level Are Related to Cognitive and Psychosocial Functioning in Adolescents. Front. Psychol. 11:1777. https://doi.org/10.3389/fpsyg.2020.01777

q3 · i? · associational · r2

Between-group ANOVA comparisons (with Bonferroni post hoc tests) among 208 adolescents divided into three weekly-exercise groups showed that "only those who engaged in a high number of hours of activity per week (Group 3) showed significant differences" on D2-TOT, D2-CON, Symbol Search, Coding, and Processing Speed; no effect sizes were printed for these cognitive contrasts.

"it is noteworthy that there were no differences between adolescents with low and moderate levels of physical exercise (Groups 1 and 2). That is, only those who engaged in a high number of hours of activity per week (Group 3) showed significant differences from those with lower levels."
