Subclaims¶
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 i3 Repeated measures ANOVA on tests 4–6 revealed a main effect of group, F(3,68) = 6.475, p = 0.001, partial η2 = 0.222, and no test × group interaction. → Limor Shtoots 2024

Omnibus repeated-measures ANOVA on post-intervention free recall (tests 4–6) in the four-group experiment, with Greenhouse-Geisser correction used at baseline. The article prints a main effect of group, F(3,68) = 6.475, p = 0.001, "partial η2 = 0.222," plus a main effect of test reflecting natural forgetting; no interaction was found.
"Repeated measures ANOVA for free recall performance on tests 4– 6 indicated a main effect of the test, F(2136) = 65.00, p < 0.001, partial η2 = 0.489 (re flecting natural forgetting over time, as anticipated), and a main effect of group F(3,68) = 6.475 p = 0.001, partial η2 = 0.222."

- Frontal theta tACS yields strong memory advantages over all other stimulation conditions at 2-hour, 24-hour, and 1-week delayed free recall tests — related
- Baseline equivalence across stimulation groups rules out prior memory-ability differences as an explanation for post-intervention effects — related
- Frontal midline theta tACS applied after learning produces significant off-line retrieval gains at all assessment time points relative to beta, parietal theta, and sham conditions — related
