q3 i? Funnel plot was relatively symmetrical; clip-and-fill adjusted the effect from 1,117 to 1,408 (both large); Rosenthal's fail-safe N was 4186 and Orwin's method required 765 zero-effect studies. → Eyüp Yurt & Seyat Polat 2015

q3 · i? · quant-synthesis · r3

Publication-bias assessment of the meta-analysis using funnel scatter plot, clip and fill, and Rosenthal and Orwin's fail-safe N methods. Clip and fill suggested 15 dummy studies; the adjusted effect size value of 1,408 still "show[s] a large effect". Rosenthal's fail-safe N was 4186.

"Then, effect size value of the studies increase to 1,408 from 1,117. According to Cohen's (1988) effect size classification, both values show a large effect."
