Reviewers also identified and classified the primary outcome according to specific criteria used previously [ 13 ] as 1 a patient-reported outcome, whereby the patient is the outcome assessor e.
We are making available draft PDF versions of these chapters to Cochrane members Login required to coincide with the Edinburgh Colloquium. Studies have described psychological distress as mood and anxiety disorders including depressive and posttraumatic symptomatology, respectively.
Grey literature includes unpublished studies, reports, dissertations, conference papers and abstracts, governmental research, and ongoing clinical trials.
This classification should help in the dissemination of these methods for trialists who perform RCTs and also the assessment of the quality of results of clinical trials for readers.
The purpose of having a protocol is to promote transparency of methods.
Is your question specific and clearly defined? It is important to know if what you need is actually a systematic review. For more details see the What's new? Strengths and weaknesses of the studies included in the review are considered.
NJIT libraries have access to about 8, e-books: Thus, we assessed a total of articles Figure 1. This type of systematic review uses statistical methods to combine the results of two or more studies. Consider the following questions before you begin.
For quantitative studies, we summarized prevalence rates and risk factors for various mental health outcomes. In evidence-based medicine, good-quality randomized controlled trials are generally considered to be the most reliable source of information about the effects of different treatments, such as drugs.
Blinding is not well understood. Click here Step 8: In fact, blinded patients may report symptoms differently from unblinded patients or have different thresholds for leaving a trial or seeking additional treatment outside a trial.
For example, unblinding may occur during the trial for patients and health care providers because of specific side effects or specific requirements such as dosage modification [ 1011 ]. 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.
Each chapter includes a discussion of common implementation mistakes using real-world examples and details what could go wrong and how to avoid these pitfalls. Why Was This Study Done? Data analysis is the next stage. The current systematic review aims to appraise and summarize findings from peer-reviewed studies pertaining to the mental health of Afghan refugees resettled in western countries, as most psychiatric surveys of refugees including Afghans have been done in these regions [ 10 ].
It is not unusual for this type of review to take months. The protocol needs to be submitted to the journal along with your manuscript. Further information is also available about the Handbook including supplementary materialinformation about what's new in each version, updates and corrections and more.
Registering your protocol is a good way to announce that you are working on a review, so that others do not start working on it. Click here Step 6: Part04 - Types of articles: Before data extraction, as a planned calibration exercise, four members of the team IB, CE, LG, and AD independently evaluated a separate set of ten reports.
Psychological distress levels in Afghan refugees may parallel outcomes from studies with other refugee populations.
Finally, they defined methods for blinded measurement of outcomes such as using a central committee to collect data. All authors should consult the Handbook for guidance on the methods used in Cochrane systematic reviews. Develop a research question 2. All potentially relevant titles were screened for inclusion.
This will assist others to understand whether any particular trial was likely to have been blinded properly, and therefore work out whether the results are reliable.A Systematic Approach to Manuscript Review In this section, we provide a systematic method for manuscript review that reflects the review template, which is included at the end of this article in Appendix 1, that is an amal- A Systematic Guide to Reviewing a Manuscript by.
Guidance notes on planning a systematic review In contrast to the traditional or narrative literature review, systematic literature reviews use a more rigorous and well- defined approach to reviewing the literature in a specific subject area.

The proposed systematic review will provide evidence regarding the effectiveness of training, therefore giving potential trainees, course designers, and decision-makers evidence to help inform their choices and policies regarding the merits of specific training opportunities or types of training.
