Subclaims¶

q3 i? Egger's regression test was non-significant (β = −0.50, p = .466), and the non-significant peer-review moderator suggested absence of publication bias. → Sangers 2025

q3 · i? · quant-synthesis · r?

Publication-bias assessment of the meta-analytic dataset: a funnel plot of overall effect sizes showed effects quite evenly distributed around the mean; excluding five outliers hardly changed the overall effect (d = 0.39), and Egger's test intercept was non-significant (β = −0.50, p =.466).

"Finally, we conducted Egger’s regression test (Egger et al., 1997), which revealed a non-significant intercept (β = − 0.50, p =.466), additionally suggesting a lack of publication bias."
