listen to the pronunciation of meta-analysis
Englisch - Türkisch
(Pisikoloji, Ruhbilim) meta-analiz
Englisch - Englisch
Any systematic procedure for statistically combining the results of many different studies
An analysis performed at a higher level of abstraction than that of basic analysis
An analysis resulting from combining the results of diverse statistical studies
A method of summarizing previous research by reviewing and combining results from multiple clinical trials Meta-analyses are attempted when previous studies were too small individually to achieve meaningful or statistically significant results Because combining data from disparate groups is problematic, meta-analyses usually are considered more suggestive than definitive
Pooled statistical analysis of results from several individual statistical analyses of different experiments, searching for statistical significance which is not possible within the smaller sample sizes of individual studies
The systematic analysis of a set of existing evaluations of similar programs in order to draw general conclusions, develop support for hypotheses, and/or produce an estimate of overall program effects
a statistical process for pooling data from many clinical trials to glean a clear answer
{i} technique or procedure of synthesizing the results of a research by combining the results of a number of independent studies
A systematic review that uses quantitative methods to summarise the results This may be achieved in several ways Examples on diagnosis of diabetes and head injury are interesting
is an overview that uses quantitative methods to summarize the results
The process of using statistical methods to combine the results of different studies For example, the pooling of results from a number of small trials, none in itself large enough to demonstrate statistically significant differences, but in aggregate, are capable of so doing
The statistical analysis of the results of a collection of individual studies for the purpose of integrating their findings
A procedure to cumulate findings from a number of validity studies to estimate the validity of the procedure for the kinds of jobs or groups of job and settings included in the studies (SIOP, 1987)
A statistical technique used to examine all research on a particular issue
Research on the research   More than a literature review, meta-analysis looks for different methodologies and measures from different people or institutions that have published research on a particular topic    After a multitude of studies on a particular subject have been reviewed, meta-analysis enables the researcher to combine the results of several studies (using quantifiable data) in order to arrive at a conclusion on the topic A researcher systematically inventories current research on a given topic and integrates the theories to arrive at a conclusion that is the sum of all the research he analyzed
A method for taking the results reported in a group of studies and 'averaging' them in a certain way to come up with a single, summary result
A mathematical or statistical analysis, used to pool the results of all studies investigating a particular effect (e g , the effect of folic acid supplementation on homocysteine levels) and provide an overall estimate of that effect
A statistical technique to combine information from many empirical studies on a topic to objectively estimate the reliability and overall size of the effect
A statistical procedure to combine results from different studies on a similar topic The combination of results from multiple studies may produce a stronger conclusion than can be provided by any singular study Meta-analysis is generally most appropriate when there are not definitive studies on a topic and non-definitive studies are in some disagreement
A quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc , with application chiefly in the areas of research and medicine [MeSH, 1989]
An overview in which quantitative methods are used to summarise the results of several studies on a single topic A meta-analysis is used in an attempt to gain greater objectivity, generalisability and precision by including all the available high quality evidence from randomised controlled trials carried out on a specified topic
The systematic, organised, and structured evaluation of a problem of interest using information from all relevant independent randomised trials It includes a qualitative component (application of predetermined criteria of scientific rigour, eg Appendix B) and a quantitative component (statistical combination of the data which can be pooled)
A method of combining the results of individual trials to allow stronger conclusions to be drawn about the effectiveness of tretments
A method for the statistical re-analysis of experimental and correlational results from independent studies that address related research questions
Data gathered entirely from existing literature using statistical methodology to integrate and summarize results of several studies The data from individual studies may be weighted by the degree of variance or other study characteristics to arrive at a pooled estimate of the relation between a factor and an outcome Usually now applied only to analysis of previously published randomized controlled trials
using statistical methods to pool samples from different studies and then try to extract conclusions that each study individually fails to prove It is a more precise estimate of the magnitude and significance of the variable being studied It involves a systematic review of studies using a quantitative procedure to combine, synthesize and integrate information across them It tries to tease out more precise information, by combining different studies
A review of a focused clinical question following rigorous methodological criteria and employing statistical techniques to combine data from independently performed studies on that question To learn more, see the User’s Guide
