q3 i? The present pooled estimate replicates the small negative relationship reported by the prior meta-analysis, which included only seven effect sizes and lacked PSU-specific search terms. → Paterna 2024

The review's Discussion compares its pooled estimate with the prior meta-analysis, which the article reports derived PSU results from a subgroup analysis using search terms that omitted PSU-specific vocabulary and included only k = 7 effect sizes.

"The magnitude of the relationship between PSU and academic achievement found in the present study is consistent with that reported in a previous meta-analytic study (Kates et al., 2018) which included notably fewer effect sizes than those considered here (i.e., K = 33 vs. K = 7)."
