Simulations show that these excess statistical significance tests often outperform the conventional Egger test for publication selection bias and the three-parameter selection model. WebMar 11, 2024 · Evidence of excess significance bias—We applied the excess statistical significance test, which evaluates whether the observed (O) number of studies with nominally significant results (“positive” studies, P < 0.05) is larger than their expected (E) number . Two-tailed P < 0.10 was considered statistically significant.
