Subclaims¶

q3 i? Publication year, sample age and percentage of females were not significantly associated with effect sizes, whereas study quality was significantly related to effect sizes. → Karle 2026 q2 i? Publication-bias indicators were mixed: Egger's mixed-effects test found no bias (z = -1.267, p = .205), Kendall's rank test found significant bias (τ = 0.080, p < .001), and PET-PEESE corrected Fisher's Z to 0.226. → Karle 2026 (2)

q3 · i? · quant-synthesis · r2

Separate mixed-effects meta-regressions for each predictor (Table 1). Post-hoc ANOVAs showed non-peer-reviewed papers did not differ from peer-reviewed ones (p = .274), nor at-risk from normal samples (p = .685). Heterogeneity was high.

"Year of publication, age, and percentage of females in the samples were not significantly associated with effect sizes. Study quality was significantly related to effect sizes."

q3 · i? · quant-synthesis · r3

Triangulated publication-bias assessment: funnel plot, Egger's mixed-effects test, Kendall's rank test, and PET-PEESE. The corrected Fisher's Z was 0.226, slightly below the uncorrected null-model estimate of 0.239.

"a mixed-effects Egger’s test for funnel plot asymmetry was run, which indicated no publication bias (z = -1.267, p = .205). However, a second analysis using Kendall’s rank test revealed significant publication bias (τ = 0.080, p < .001)."
