How to Collect Data & Write a Meta-Analysis Article for Scopus/WOS Publication: A Real Example Video

Analyzing partial correlation coefficients for meta-analysis involves a systematic process to combine and interpret results from multiple studies. Here's a step-by-step guide:
Step 1: Define the Research Question and Inclusion Criteria
Clearly articulate your research question and establish inclusion criteria for selecting studies. Ensure that studies meet the criteria for partial correlation analysis.
Step 2: Literature Search
Conduct a comprehensive literature search using databases like PubMed, Google Scholar, or specialized platforms. Identify relevant studies that report partial correlation coefficients related to your research question.
Step 3: Data Extraction
Collect essential information from each selected study, including sample size, partial correlation coefficients, standard errors, and relevant contextual details. Organize the data in a structured manner.
Step 4: Convert Correlation Coefficients to Fisher Z Scores
Since correlation coefficients typically follow a skewed distribution, it's common to transform them into Fisher Z scores for analysis. Use the formula:
\[ Z' = 0.5 * \ln\left(\frac{1 + r}{1 - r}
ight) \]
where \(r\) is the correlation coefficient. This transformation stabilizes variances and is more suitable for meta-analysis.
Step 5: Conduct Meta-Analysis
Perform the meta-analysis using statistical software such as R, Python (with packages like metafor), or specialized meta-analysis software. Calculate the overall effect size (combined Fisher Z) and associated confidence intervals.
Step 6: Assess Heterogeneity
Evaluate heterogeneity among the studies using measures like \(I^2\) and Cochran's Q test. High heterogeneity may indicate variations in study characteristics or populations.
Step 7: Subgroup Analysis and Sensitivity Analysis
Explore potential sources of heterogeneity through subgroup analyses based on study characteristics. Perform sensitivity analyses to assess the impact of individual studies on the overall results.
Step 8: Publication Bias Assessment
Evaluate publication bias by generating funnel plots and conducting statistical tests (e.g., Egger's test). Publication bias can affect the reliability of meta-analysis results.
Step 9: Interpretation and Conclusion
Interpret the combined effect size and associated confidence intervals. Discuss the implications of the findings in the context of the research question. Highlight limitations and propose future directions for research.
Step 10: Reporting
Present your meta-analysis results in a clear and transparent manner. Use tables, forest plots, and other visual aids to communicate findings effectively.
Remember, conducting a meta-analysis requires a good understanding of statistical methods, and it's advisable to consult with a statistician or someone experienced in meta-analysis during the process.

I don't know how to thank you. A simple explanation is what works the best. Thank you Dr.

[@Dr.Munshi-Naser]

So kind of you

[@fluteworld8687]

We are blessed to have a genuine person like you. Thankyou so much for being what you are sir.
🙏🙏

[@Dr.Munshi-Naser]

Thanks dear 🙏

[@Misha0336]

Sir thank you sp much for this video. Can you explain about data analysis for beginners jn research?

[@WisdomofImamAli]

Sir, it's a really amazing tutorial, How I could approach you I need to learn more things about meta-analysis?

@@Dr.Munshi-Naser sir please check your email I sent an email from Sajid Hussain

[@mulyadimanik7489]

Thanks, could you create same video but in Agriculture sector?

[@Dr.Munshi-Naser]

Will try.

[@JONYHANNAN]

Thank you sir for your nice video! My topic is "Revenue Generation and Revenue Elasticity". I'm searching based on revenue generation and revenue elasticity separately to collect and sort papers. Is this okay to start? Please give your views.

[@Dr.Munshi-Naser]

Start first and let me know how far you have achieved. Thank you

How can i use meta analysis for food disease

[@Dr.Munshi-Naser]

I will share a video on this soon.
