A primary Article is an article where the author does the research themselves. It entails a supporting a new set of findings or data from original research. These papers can explore new ideas or theories or can test old ideas or theories. The only thing that really matters is that a new experiment or research is done on the topic.
A review Article is a summary and analysis of current information. It does not report on any new experiments, data, research, or findings. It reviews all available sources to prove or disprove ideas based on the analysis of current papers.
The peer review process starts when the author of a paper submits their manuscript to a publishing company, or journal. The next step is where an editor checks for plagiarism and major errors. If there are major problems or plagiarism then the paper will be rejected. The author of the paper can revise and resubmit the paper again. If the paper is accepted then it will be sent to a peer review committee. A peer review is when a group of experts analysis the content (data, findings, accuracy) of a paper. If the paper is reject it can be revised to be submitted again. However, if a paper is accepted then it will get published with either minor to no changes. After, any changes that may need to be made are fixed the paper is published to a journal or other publishing company.
The first major difference between a review and a primary article is that a review article does not have a methods, materials, or results section. Since a review article analysis existing data it does not need a methods or results section. The next difference is that primary article has a clear independent variable, dependent variable, and control because it is on a single experiment. However a review article looks at multiple articles which all have their own controls, independent variables, and dependent variables. Since a review essay analysis other peoples work it has a lot of in-text citations, and references. Primary review articles however do not usually have a lot of in-text citations if any because it is original findings, and a new experiment. Finally, review articles tend to have a lot of meta-analysis or systematic analysis since they are looking through and making connections between different research papers.
“An mRNA Vaccine against SARS-CoV-2- Primary Report” is a primary article. It has a methods and results section. It has very few in-text citations (I think I only see one towards the end). It has a clear independent variable, dependent variable, and control. On the other hand “Covid-19 vaccine: A recent update in pipeline vaccines, their design and development strategies” is a review article. It has no methods, and results section. It has a lot of in-text citations. In fact almost every paragraph has at least two in-text citations. There is not single independent variable, dependent variable, or control. The paper is sole analysis on a number of papers.
