Subclaims¶

q3 i? Egger's three-level regression test indicated significant publication bias for the overall analysis (t = -2.33, df = 140, p = .02) but not for fluency, flexibility, or originality taken separately. → Said-Metwaly 2019

q3 · i? · quant-synthesis · r3

Publication-bias analysis in Results using funnel-plot inspection and a three-level extension of Egger's regression test. The overall analysis showed significant bias (t = -2.33, p = .02); the indicator-level tests were non-significant. No effect size is printed.

"The Egger’s test showed that publication bias was significant for the overall analysis (t = -2.33, df = 140, p = .02), but not for fluency (t = -0.91, df = 39.10, p = .37), flexibility (t = -1.48, df = 36.90, p = .15), or originality (t = -0.57, df = 40.50, p = .57) taken separately."
