A file drawer analysis would be the appropriate choice to determine the number of null results that would have to exist to overturn any statistically significant effect found in the meta-analysis. This type of analysis involves examining the possibility of publication bias, where studies with null results may not have been published or included in the meta-analysis, potentially skewing the overall effect size. By assessing the number of unpublished studies that would need to exist to diminish the observed effect size, the researcher can determine if the results of the meta-analysis are robust or if publication bias may be a concern.
