What Are Five Different Types Of Systematic Reviews?

Systematic Reviews


The systematic review summarizes the evidence on specific criteria. Its scope lies in the research questions of the study. Researchers try their best to find the relevant data. They use different sources. They define criteria for the acceptance of information. Quality of study increases due to these standards. It makes the study more specific. Researchers follow the pattern and share their findings in a great way. A systematic review uses to identify and sum up the information about the study aim. They use the study to highlight the basis for the knowledge. These bases are helpful to explain the issue to readers. Many people raise objections to systematic reviews. They consider its main feature as its limitation. They show concern that it focuses on answering specific questions. Besides, most of the researchers use it. Systematic reviews have many types. In this article, we are going to share five types of it.

Scoping Review

The assignment help firm gives an idea about the topic. It tells the researcher that you have to work on an idea or not. It helps in finding evidence about the topic. It is exploratory in nature. It answers the broad question about the topic. It assesses the availability of the evidence. Moreover, it helps in organizing them. It also highlights the gaps in the topic. It also shows that it is right to conduct a systematic review or not. It is also based on specific criteria. Researchers review the literature and find relevant proof. This review type explores the situation. Its result helps do a systematic review. It also highlights the time for conducting a systematic review. It deals with a large amount of data. So, it takes a lot of time to do this.

Rapid Review

It simplifies the process of a systematic review. It provides information to make decisions on time. Policymakers and others are having less time using it. Evidence-based information proves helpful in taking decisions. It varies according to the researcher's needs. The researcher can use it to find different kinds of information. It is not only useful in answering broad questions. But it also shows good insights about critical issues. It is also good to find information about emerging topics. It makes the systematic review easy. It takes off many stages of the systematic review (Dobbins, 2017). In this way, they make their process easy to work. Search on information is not enough in it. Many times, single researchers do it. It affects the credibility of the review. Explanation of the finding is also limited in rapid review.

Narrative Review

It is the basic type of review. Many research students practice it in their universities. The purpose of it is to find a few studies that explain the main issue. It focuses on the main issue. You don’t have to build a research question for doing this review. It also does not follow any specific standard. It takes the broader picture of the topic. It gives some basic idea about the problem. It does not give a complete understanding of the topic. But it enables researchers to learn about the issue. Researchers start the review by identifying the main topic. Then they start searching for data about it. They identify and use keywords to find relevant topics. But they don’t try to find precise data. They use generic keywords to get the wider picture. They don’t read the articles in depth. But they only take the idea by reading the abstract and conclusion. After that, they sum up the findings of the article to get the narrative of the topic.


It is the process of merging the results of different studies. It uses different statistical approaches to find the effect. It is not about summing up the data from small to larger size. It provides a precise estimate of the data. It also has many types according to its effect. Researchers use it according to the need of an hour. Sometimes it also includes subgroup analysis. They do it to understand the effect of factors on relationships. It is an important type of systematic review. Searching the literature is the first step in meta-analysis. It also has significant importance. If you fail to do a good search, the analysis may show wrong results. It also identifies the statistical measure used in different studies. And then check the weighted average f this measure. Many expert researchers use it to show great insights about the topic.

Mixed Methods

It is the popular type in today’s world. It integrates the quantitative and qualitative data. It gives a complete picture of the data. This is because it includes both types of data. It ends the debate of the researchers. Some support quantitative while others support qualitative data. Mixed studies add the point of both of them. It covers the rigorous approach of both types (Almeida, 2018). It integrates the data is not only the collection stage but also the analysis stage. Some researchers collect quantitative first and then collect qualitative data. In contrast, some researchers adopt the opposites technique for data collection. They also overcome the drawbacks of each other. For example, qualitative data explain the results of quantitative data. Yet, it increases the complexity. You also have to spend a lot of time searching.


For doing a literature review, an essay writing service review is popular all over the world. It sums up the results by following the specific pattern. Meeting the standard of review increases the worth of data. It increases the quality of data. Researchers do systematic research by using its different types. Scoping review is one of the popular types. It gives the researcher an idea about further pursuing the topic or not. Rapid review and meta-analyses are also famous among researchers. A narrative review and mixed methods are more common among researchers. Students also use it on their research projects. Researchers can use them according to the research aims.
