1. Which visual representation is used to detect publication bias by plotting study effect sizes against their standard errors?

   1. Funnel plot
   2. Begg's funnel
   3. Forest plot
   4. Egger's triangle

2. What does the Egger test specifically assess in a meta-analysis?

   1. The average effect size across all studies
   2. Whether small studies show systematically larger effects
   3. The quality of individual studies
   4. Heterogeneity between study results

3. P-curve analysis detects publication bias by examining what characteristic of the distribution of p-values?

   1. The number of studies with p > 0.05
   2. The skewness toward significant p-values
   3. The average p-value across studies
   4. The variance in p-values between studies

4. What is the primary purpose of searching grey literature in a meta-analysis?

   1. To identify authors for collaboration
   2. To find studies published in predatory journals
   3. To locate additional funding sources
   4. To find unpublished studies that might show different results

5. Which statement best describes what AI cannot accomplish in publication bias detection?

   1. AI can completely eliminate publication bias from any meta-analysis
   2. AI can determine which studies were deliberately withheld
   3. AI cannot find studies that were never made publicly available
   4. AI can identify all instances of questionable research practices

6. Why is documenting the publication bias detection methodology important in a meta-analysis?

   1. It allows others to reproduce and verify the bias assessment
   2. It increases the statistical power of the analysis
   3. It automatically corrects for detected bias
   4. It reduces the need for peer review

7. What does sensitivity analysis test in the context of publication bias detection?

   1. How robust findings are to different bias assumptions
   2. Whether the sample size is adequate
   3. If the effect size is clinically significant
   4. Whether studies meet inclusion criteria

8. What is a fundamental limitation of relying solely on statistical detection methods for publication bias?

   1. Statistical methods work equally well for all study types
   2. Statistical methods always produce definitive results
   3. Statistical detection cannot substitute for substantive evaluation of the research
   4. Statistical detection eliminates the need for expert review

9. Which type of study is most likely to be missing from a published meta-analysis due to publication bias?

   1. Meta-analyses with large sample sizes
   2. Studies with non-significant or negative findings
   3. Studies published in high-impact journals
   4. Large randomized controlled trials

10. What does a flat p-curve suggest about a set of studies?

    1. The studies definitely have publication bias
    2. The studies may have questionable research practices
    3. The studies show a strong true effect
    4. The studies are all high quality

11. How do AI-assisted methods extend traditional publication bias detection?

    1. By guaranteeing that no bias will affect results
    2. By applying traditional methods at scale and identifying patterns humans might miss
    3. By eliminating the need for traditional statistical tests
    4. By automatically publishing missing studies

12. In a funnel plot, what does asymmetry typically indicate when the left side is empty?

    1. The meta-analysis has high statistical power
    2. All relevant studies were included
    3. There is no publication bias present
    4. Studies with negative or null results may be missing

13. What is required for a meta-analysis to be considered valid despite detected publication bias?

    1. The absence of any detected bias
    2. The inclusion of at least 50 studies
    3. Proper documentation and transparent reporting of detection methods
    4. The use of only AI-assisted methods

14. Which of the following is an example of grey literature?

    1. A doctoral dissertation summarizing research findings
    2. A textbook chapter on research methods
    3. A systematic review published in a database
    4. An article in a peer-reviewed journal

15. What aspect of publication bias does p-curve analysis specifically help detect?

    1. Bias in study funding sources
    2. Citation bias toward highly-cited articles
    3. The presence of p-hacking or other questionable research practices
    4. Language bias in international studies
