Metaanalysis might also be carried out. The discussion section should also be clearly ordered. Methodology and potential bias might also be listed. The methodology should be clearly defined before starting, in order to minimise bias.
This stage also involves screening for and removing duplicates. Such a form means data can also be entered into a database, making future use easier. A simple form of data analysis is to descriptively evaluate the studies, summarising these in table format. Different types of systematic review demand different forms, so ensure you use the most correct type.
The final paragraph sets out conclusions and implications. Data extraction can be done using a standardised form. Such tables typically include the population studied, interventions and outcomes.
Writing up a Systematic Review Systematic reviews follow a clear structure, generally of the format The title should be concise and accurate The abstract should be clearly structured The introduction should summarise the topic and explain why the review is necessary.
It should be kept in mind, however, that different checklists can produce very different results. The next paragraph describes limitations of studies included and of the review process. It starts with a summary statement setting out the main finding.
The aim of searching the literature is to produce an inclusive list of relevant research studies from which to select the studies included in the review.
Inclusion and exclusion criteria should also be determined at this stage.
The question should be clearly focussed, neither too narrow nor too broad. This section covers the number of studies found, how many excluded, details of study range and characteristics, study quality, and so on.
Data analysis is the next stage. It is wise to use more than one online database as each one includes a different range of journals. This stage forms part of a larger stage of devising the research protocol.
Recommendations for future studies are often made. On the basis of quality appraisal, studies are rejected and accepted. This can be done through a computer based reference management system such as EndNote. This links to a simple and easy to understand example: Strengths and weaknesses of the studies included in the review are considered.
The findings of the studies are summarised, and conclusions indicated. The acronym PICO has been devised to summarise the four parts a question should take into account the population or patient group studied, the intervention, treatment or test, a comparison or alternative intervention, and the outcome of the intervention see figure 1 for an example The research protocol covers the methods for searching the literature and extracting and analysing the data.
Reference lists of articles are useful for finding new areas to investigate, as can handsearching of journals. Bibliographic databases including Pubmed, Medline, the Cochrane Library and Embase for healthcare can be used. Quality appraisal is perhaps the most central step, and there are a number of checklists which have been developed to help with this process.
This links to an example of such a form: The results are then interpreted. The third paragraph should cover the negative and positive aspects of the methodology, while the fourth paragraph contexualises the results in terms of existing knowledge.
Results Conclusion The first step is to formulate a research question. The literature search is the next step.A systematic review is a highly rigorous review of existing literature that addresses a clearly formulated question. Systematic reviews are regarded as the best source of research evidence.
This article discusses the types of systematic review, systematic review protocol and its registration, and the best approach to conducting and writing a systematic review.
