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 i2 The generation effect was larger in studies published 1982–2000 (g = 0.63) than in studies published 2001–2019 (g = 0.28), and publication year had a stable negative effect across all six meta-regression models. → Julia Schindler · Tobias Richter 2023

Subset moderator analysis splitting studies at the year 2000, plus meta-regression. The article reports that publication year had a stable negative effect in all six meta-regression models, indicating older studies yielded stronger effects than newer studies.

"We found a significant effect of publication year when studies were split into two groups, until and after the year 2000. The effect was larger in earlier studies (g = 0.63, p < 0.001) compared to studies that appeared after the year 2000 (g = 0.28, p < 0.001)."
