The aim of the PRISMA statement is to help authors improve the reporting of systematic reviews and meta-analyses. [3] PRISMA has mainly focused on systematic reviews and meta-analysis of randomized trials, but it can also be used as a basis for reporting reviews of other types of research (e.g., diagnostic studies, observational studies).
A meta-analysis of such expression profiles was performed to derive novel conclusions and to validate the known findings. [148] Meta-analysis of whole genome sequencing studies provides an attractive solution to the problem of collecting large sample sizes for discovering rare variants associated with complex phenotypes.
A meta-analysis with some or all studies having more than two arms is called network meta-analysis, indirect meta-analysis, or a multiple treatment comparison. Despite also being an umbrella term, meta-analysis sometimes implies that all included studies have strictly two arms each—same two treatments in all trials—to distinguish itself ...
Examples of such works are scientific reviews and meta-analyses. These and related practices face various challenges and are a subject of metascience. Various issues with included or available studies such as, for example, heterogeneity of methods used may lead to faulty conclusions of the meta-analysis. [115]
For example, if both p-values are around 0.10, or if one is around 0.04 and one is around 0.25, the meta-analysis p-value is around 0.05. In statistics , Fisher's method , [ 1 ] [ 2 ] also known as Fisher's combined probability test , is a technique for data fusion or " meta-analysis " (analysis of analyses).
A metatheory or meta-theory is a theory on a subject matter that is a theory in itself. [1] Analyses or descriptions of an existing theory would be considered meta-theories. [ 2 ] If the subject matter of a theoretical statement consists of one or multiple theories, it would also be called a meta-theory. [ 3 ]
"Meta" is Greek for "beyond"; "narrative" is a story that is characterized by its telling (it is communicated somehow). [6]Although first used earlier in the 20th century, the term was brought into prominence by Jean-François Lyotard in 1979, with his claim that the postmodern was characterized precisely by mistrust of the "grand narratives" (such as ideas about Progress, Enlightenment ...
A research proposal is a document proposing a research project, generally in the sciences or academia, and generally constitutes a request for sponsorship of that research. [1] Proposals are evaluated on the cost and potential impact of the proposed research, and on the soundness of the proposed plan for carrying it out. [ 2 ]
