Should Meta Analysis be registered?

I often encounter students who ask: is it necessary to register for Meta analysis? For an answer to this question, take a look at how the reporting standard "PRISMA" of Meta analysis requires:

Indicate if a review protocol exists, if and where it can be accessed (e.g.Web address), and, if available, provide registration information including registration number.

In other words, in the methodology section, you need to explain whether the research plan exists, and if so, you need to provide access to the URL or registration information, including the registration ID number.

But in the actual process, we will also see that some Meta analysis has been published without registration, including some high-scoring magazines, in fact, there are many reasons, among which the requirements of magazines and the preferences of reviewers are the biggest factors. Some magazines require the author to provide a registration ID number, and some strict reviewers may question why you did not register. Therefore, in the actual process to ensure foolproof, especially now more and more standardized circumstances, it is recommended that you must register before writing Meta analysis, whether in Chinese or English.

So why would a magazine or academia recommend Meta analytics registration? What are the benefits of registering for Meta analytics?

In fact, the reason for registering Meta analysis is the same as registering for clinical trials. Registering Meta analysis can help us to achieve: 1. Record the topic. Through the registration of Meta analysis, the author clarifies the background significance and implementation steps of the project, which is convenient for the follow-up actual operation process.

2. Prevent the author from changing the original scheme for some reason and reduce selective reporting. If the Meta analysis does not have a plan in advance, it is easy for the author to modify the inclusion and exclusion criteria, or even the data, at a later stage in order to get a good result. Therefore, this situation can be effectively avoided through registration. By comparing the research plan with the completion of the paper, we can find out whether there is a selective report.

3. Avoid the crash of the project. This is equivalent to making your idea public in advance and avoiding repeating it with others. It is an effective way to prevent you from finding that a paper on the same topic has been published in the middle of your paper. (the role in the actual process is debatable.)

4. Increase the credibility of the article and increase the chance of publication. Because some magazines need to register for ID.

How to register?

At present, there are two commonly used Meta analysis registration platforms in academic circles: Cochrane library and PROSPERO registration platform.

However, the Cochrane system evaluation registration platform is purely closed, and all processes need to contact the Cochran collaboration network to go through the process of registering topics, writing research plans and writing the full text of the system review. at the same time, due to three reviews and strict requirements, it generally takes a long time, and can not complete a systematic review in less than 2 years, but it also has a lot of benefits. In this process, you can receive legal guidance from experts from Cochrane collaboration Network, which will help you to have a deeper understanding of the statistical methods of Meta analysis, and once accepted, the paper will be published in the Cochrane Library (IF=7.755), and there is a trend of increasing year by year.

In practice, most people will prefer the PROSPERO registration platform, which is an international database containing forward-looking registration system reviews of health and social care, welfare, public health, education, crime, justice and international development, aimed at providing a systematic review research plan by comparing the completed systematic review with the content planned in the programme. Help avoid repetition and reduce the chances of reporting bias. It is similar to the purpose of the Cochrane registration platform, but the steps are very simple, just sign up for an account and submit a research plan for review, often in about two months. (don't worry after that, just wait.)

(Corrigendum: the Cochrane impact factor in the picture is 2017, and 7.755 in 2018)

When will you register? Bring this question out alone, because many students do not realize the importance of Meta analysis registration, wait until the paper has been written, then ask, Meta analysis can not register? Will it affect the publication? This actually brings us back to our first question. So here we need to emphasize the registration time of Meta analysis.

The following figure shows PROSPERO's requirements for registration time: 1.Meta analysis needs to be registered after the research plan has been written, but preferably before screening the literature, it is also acceptable to register before the information extraction is completed. two。 Completed system reviews should not be registered, and Cochrane system reviews do not need to be registered on PEROSPERO.

Therefore, after knowing this point in time, I believe you will better understand the significance and timing of Meta analysis registration.

Frequently asked questions

In the actual registration process, some students will have three questions:

1. Meta analysis after registration, will anyone see that my idea is better and write papers non-stop before I publish? A: in fact, it is possible that this possibility exists, because the registration of Meta analysis is not a mandatory requirement at present, so it is possible for others to see that your idea has published your paper ahead of time. There are two solutions: 1. The editorial department wrote a letter stating that you have registered this Meta analysis in advance, and will withdraw the manuscript in response to your request if the editorial department attaches great importance to it. Find the reason from yourself, why do you register first and others finish first, so you need to remind everyone that the literature included in Meta analysis is timely, and it is best to publish the paper within a year, so the writing process must be fast, otherwise you may have to add and retrieve the literature again and again when you review the manuscript. 2. What if there is no registration after the Meta analysis is written? Answer: the answer to this question is to remind everyone to strictly follow the steps of Meta analysis. If there is no registration and the other magazine does not have a mandatory requirement, it can also be published, but if there is an impact on publication, you can re-register in PROSPERO, and select the time period before data extraction at the time of registration to meet the registration requirements, but strictly speaking, this method is an illegal operation. Does not conform to the academic standard, but also asks everybody to use carefully! 3. Can it be modified after Meta analysis registration is completed?

Answer: although the purpose of Meta analysis registration is to prevent the author from temporarily modifying the research plan due to the progress of the project, in the actual process, we find that the author can update the progress and content of Meta analysis, but we need to explain the reasons, so if you need to modify, you can directly modify and submit the reasons on the web page, including the progress of the project can also be updated on the website. The above is how Meta Analytics is registered. Have you learned any knowledge or skills?
