Systematic Review and Meta analysis - All you ever need to know
Meta analysis is a very common way of bringing together data to help us decide which treatments might be best. BUT, you have to take care when interpreting them - there's a lot more to it than just looking which side of the line the little black diamond is on! How do you construct a search for a systematic review?Can you trust the result of a meta analysis? How do you know if it has been done well? How to recognise different kinds of bias, how to interpret a forest plot, and funnel plot and a bubble plot. What is the I squared statistic and what does it tell you about the data and how much to trust the result? These and many more things to do with these common but complex analyses is explained by Brett Doleman, statistical guru!

How to write a literature review
How to write a literature review. It’s easier than you might think! In this video, I demonstrate how to search the literature and identify relevant papers for your literature review. I do a pubmed search using Boolean operators and MeSH terms (these are extremely powerful tools that will help you sift through the large number of academic papers out there). So if you’re doing a master’s thesis or a PhD, or you’re doing research and writing a paper, at some point, you’ll need to do a lit review. A big part of that review is the search and this video is going to help you get that right. You might be doing a systematic literature review or meta-analysis – again, you’ll need to do a good PubMed search that identifies the right studies. Thanks to BMC !!! ----------------------------- This video was sponsored by BMC – (click here to go to BMC: https://goo.gl/RFaUA2 ). As a pioneer of open access publishing, BMC has an evolving portfolio of high-quality peer-reviewed journals including broad interest titles such as BMC Biology and BMC Medicine, specialist journals such as Malaria Journal and Microbiome, and the BMC series. BMC is committed to continual innovation to better support the needs of research communities, ensuring the integrity of the research we publish, and championing the benefits of open research. BMC is part of Springer Nature, giving us greater opportunities to help authors connect and advance discoveries across the world. I’m particularly excited about having BMC’s support because I’ve been working with them for nearly 15 years as the Editor-in-Chief of the journal Globalization and Health. I’ve been extremely impressed by them as a company that has integrity and that is truly making the world a better place. LEARN MORE about literature reviews ------------------------------------------------------------ Of course, there is more to a literature review than just the search. You need to have a structured approach to selecting paper, extracting data, writing the review itself and creating a bibliography. For more detail on these aspects of a literature review, go to www.learnmore365.com where I have a full course on literature review (it takes about 30 minutes to complete).

What is META-ANALYSIS? What does META-ANALYSIS mean? META-ANALYSIS meaning & explanation
What is META-ANALYSIS? What does META-ANALYSIS mean? META-ANALYSIS meaning - META-ANALYSIS definition - META-ANALYSIS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The basic tenet of a meta-analysis is that there is a common truth behind all conceptually similar scientific studies, but which has been measured with a certain error within individual studies. The aim in meta-analysis then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. In essence, all existing methods yield a weighted average from the results of the individual studies and what differs is the manner in which these weights are allocated and also the manner in which the uncertainty is computed around the point estimate thus generated. In addition to providing an estimate of the unknown common truth, meta-analysis has the capacity to contrast results from different studies and identify patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies. Meta-analysis can be thought of as "conducting research about previous research." Meta-analysis can only proceed if we are able to identify a common statistical measure that is shared among studies, called the effect size, which has a standard error so that we can proceed with computing a weighted average of that common measure. Such weighting usually takes into consideration the sample sizes of the individual studies, although it can also include other factors, such as study quality. A key benefit of this approach is the aggregation of information leading to a higher statistical power and more robust point estimate than is possible from the measure derived from any individual study. However, in performing a meta-analysis, an investigator must make choices many of which can affect its results, including deciding how to search for studies, selecting studies based on a set of objective criteria, dealing with incomplete data, analyzing the data, and accounting for or choosing not to account for publication bias. Meta-analyses are often, but not always, important components of a systematic review procedure. For instance, a meta-analysis may be conducted on several clinical trials of a medical treatment, in an effort to obtain a better understanding of how well the treatment works. Here it is convenient to follow the terminology used by the Cochrane Collaboration, and use "meta-analysis" to refer to statistical methods of combining evidence, leaving other aspects of 'research synthesis' or 'evidence synthesis', such as combining information from qualitative studies, for the more general context of systematic reviews.

NCCMT - URE - Types of Reviews - What kind of review do we need
Do you know when to use different types of reviews in public health decision making? Do you know the differences between a literature review, a systematic review, and a meta-analysis? Using an imaginary campaign to promote of healthy eating among adolescents as an example, this video describes how these reviews are created. You will see why combining findings from studies gives you a more accurate and generalizable understanding of what to expect from an intervention. Systematic reviews combine relevant research studies in a systematic way to answer a specific research question with minimal bias. They tell you whether or not an intervention is effective. Meta-analyses are similar to systematic reviews, but go one step further: they provide a numerical summary of the combined findings. In addition to whether or not an intervention works, meta-analyses can tell you the size of the intervention effect. Literature reviews, on the other hand, summarize multiple studies without using a systematic process for identifying, including, or combining studies. This type of review can lead to biases in the summary. Different types of reviews can affect how much confidence you can have in the findings. There can be thousands of single studies that each look at small portions of the population. Systematic reviews and meta-analyses can provide information based on all available studies making them powerful aids for evidence-informed decision making in public health.

KTDRR Research Evidence Training: An Overview of Effect Sizes and Meta-analysis
In this KTDRR webcast, Drs. Ryan Willams and Josh Polanin give an Overview of Effect Sizes and Meta-analysis. Systematic review and meta-analysis are techniques used to synthesize and summarize large bodies of research literature. Compared to results from a single primary study, meta-analysis provide greater generalizability, increased precision, and the ability to explore heterogeneity across studies (Borenstein, Hedges, Higgins, & Rothstein, 2010; Pigott, 2012). In this Webcast, we will provide participants with an overview of the foundation of meta-analysis, an effect size, which is a quantitative indicator of a treatment effect or relation between two variables. We will also explicate the basic processes of a meta-analysis and how the technique can be used to answer complex questions asked by policymakers and practitioners.
