You will have difficulty selecting a TV show to watch from the massive array of possibilities, for example, if the shows differ from each other in multiple ways or if you don’t have any strong preferences when you finally get to sit down in front of the TV. The meta-analysis revealed that choice overload exists-but only under certain conditions. For example, to clarify whether or not having more options makes it harder for people to settle on any one item, a meta-analysis of over 53 conflicting studies on the phenomenon was conducted.

The technique can be used to answer social and behavioral questions large and small. In reviewing the aggregate results of well-controlled studies meeting criteria for inclusion, meta-analysis can also reveal which research questions, test conditions, and research methods yield the most reliable results, not only providing findings of immediate clinical utility but furthering science. Meta-analysis is often used to validate observed phenomena, determine the conditions under which effects occur, and get enough clarity in clinical decision-making to indicate a course of therapeutic action when individual studies have produced disparate findings. Meta-analyses, and the questions they are attempting to answer, are typically specified and registered with a scientific organization, and, with the protocols and methods openly described and reviewed independently by outside investigators, the research process is highly transparent. However, the accuracy of meta-analysis can be attenuated in the presence of cross-study heterogeneity. Similar to a narrative review, it serves as a synopsis of a research question or field.

Through statistical methods applied to the original data collected in the included studies, meta-analysis can account for and overcome many differences in the way the studies were conducted, such as the populations studied, how interventions were administered, and what outcomes were assessed and how. Meta-analysis has been established as an effective approach to combining summary statistics of several genome-wide association studies (GWAS). Meta-analysis is a central method for knowledge accumulation in many scientific fields (Aguinis et al. For example, cohort studies are likely to provide more reliable information than case reports. Considering that a systematic review 10 is fundamental for a meta-analysis, you can use the Population, Intervention, Comparison, Outcome (PICO) model to formulate the research question. In addition, published guidelines not only describe standards for the inclusion of studies to be analyzed but also rank the quality of different types of studies. Rule 1: Specify the topic and type of the meta-analysis. Usually, meta-analysis is conducted on the gold standard of scientific research-randomized, controlled, double-blind trials.

Meta-analysis is a statistical method that allows researchers to combine and analyze data from many different studies. There are well-established scientific criteria for selecting studies for meta-analysis. Recently, studies using meta-analysis have summarized the large amount of data generated from these experiments over the years to give us a better picture of the general conclusions.
