Meta-analysis 101: What, Why, and How

By Hassam Waheed,

The number of published meta-analyses have increased exponentially over the decades, and are the most cited form of academic papers. Meta-analysis is a popular statistical technique for summarizing, integrating, and interpreting empirical research. Since a meta-analysis aggregates conceptually and statistically similar studies, it offers greater statistical power to detect relevant effects than any single study. Through a meta-analysis, a researcher is able to answer questions that may not be possible to answer in any single study. Resultantly, a meta-analysis takes the top spot in a hierarchy of evidence-based research, followed by systematic reviews and randomized controlled trials (RCTs). The aim of this seminar is to provide a basic overview of a meta-analysis to undergraduates, postgraduates, academics and researchers who have no prior meta-analyzing experience. Upon completion of this seminar, participants should be able to:

• Demonstrate an understanding of the purpose of a meta-analysis – “What”
• Define a research question for their meta-analysis – “Why”
• Know how to perform a meta-analysis – “How”

Great. But what is the total effect size? is it the summation of multiplication of inverse variance and fisher z of all the studies?

[UdayKiranKommuriPHD]

Sir, for meta-analysis, do we have to follow the PRISMA framework. How to collect the data and what methods can be used to write the data. is it the same as systematic review, where we include all the data in excel or do we need to adopt any software?. kindly Guide Sir.

Sir, I am very thankful for your Guidance for systematic review. I have followed the steps as given in the video and submitted it for publication.
