Competing interests: The authors have declared that no competing interests exist. In the context of evidence-based medicine, meta-analyses provide novel and useful information meta analysis dissertation 1 ], as they are at the top of the pyramid of evidence and consolidate previous evidence published in multiple previous reports [ 2 ]. Meta-analysis is a powerful tool to cumulate and summarize the knowledge in a research field [ 3 ].
Because of the significant increase in the published scientific literature a great resume format recent years, there has also been an important growth in the number of meta-analyses for a large number of topics [ 4 ]. It has been found that meta-analyses are among the types of publications that usually receive a larger number of citations in the biomedical sciences [ 56 ].
The methods and standards for carrying out meta-analyses have evolved in meta analysis dissertation years [ 7 — 9 ]. Although there are several published articles describing comprehensive guidelines for specific types of meta-analyses, meta analysis dissertation is still the need for an abridged article with general and updated recommendations for researchers interested in the development of meta-analyses. We present here ten simple rules for carrying out and writing meta-analyses. 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.
It is important to verify that there are no published meta-analyses on the specific topic in order to meta analysis dissertation duplication of efforts [ 11 ]. Undergraduate history dissertation prize some cases, an updated meta-analysis in a topic is needed if additional data become available. It is possible to carry out meta-analyses for multiple us resume writing service of studies, such as epidemiological variables for case-control, cohort, and textos dissertations exemplos clinical trials.

Keep in mind that the current consensus advises against strict criteria concerning language or sample size. You should clearly define the variables that will be extracted from each primary article. Broad inclusion criteria increase heterogeneity between studies, and narrow inclusion criteria can make it difficult to find studies; therefore, meta analysis dissertation compromise should be found.
Prospective meta-analyses, which usually are carried out by international consortia, have the advantage of the possibility of including individual-level data [ 20 ]. Usually, searching in several databases helps to minimize the possibility of meta analysis dissertation to identify all published studies [ 22 ]. Moreover, in other cases, direct search for the data is also advisable i. Usually, the bibliography order world affairs thesis statement review articles might help to identify additional articles and data from other types of documents such as theses or meta analysis dissertation proceedings that might be included in your meta-analysis.
The Web of Science database can be used to identify publications that have cited key articles. Adequate extraction and recording of key data from primary articles are fundamental for carrying out a meta-analysis. Quality assessment of the meta analysis dissertation studies is also an important issue; it can be used for determining inclusion criteria, sensitivity analysis, or differential weighting of the studies. It is recommended that these steps be carried out by two researchers meta analysis dissertation parallel and that discrepancies be resolved by consensus.
In any case, it is important to avoid the confusion of using guidelines for the reporting of primary studies as scales for the assessment of the quality of included articles [ dissertations for nova southeasternuniversity for1995 for martha smith-taylor30 ].

For more complex data, multivariate methods meta analysis dissertation meta-analysis have been proposed [ 4546 ]. Additional statistical examinations involve sensitivity analyses, metaregressions, subgroup analyses, and calculation of heterogeneity metrics, such as Q or I 2 [ 20 ].
Meta analysis dissertation is fundamental to assess and, if present, explain the possible sources of heterogeneity. Although random-effects models are suitable for cases of between-studies heterogeneity, the sources of between-studies variation should be identified, and their impact on effect size should be quantified using statistical tests, such as subgroup analyses or metaregression.
