Table 4.

95% one-sided confidence limits above which the estimated N _R is significantly higher than 5k + 10, which is the rule of thumb suggested by Rosenthal [11]. k represents the number of studies included in a meta-analysis. We choose the variance from a fixed number of studies when the Z _i are drawn from a half normal distribution HN(0, 1), as this performed best in the simulations.
