In the RG discussion, I left some links that may be helpful for your question. Good luck.

Without any doubt review papers are also part of the state of the arts in any subject you are preparing your review study. You may use them as part of the references to use in your paper, but more as a guide to know and find the novel issues on your own and to update them through your survey. Nevertheless, most of the references used in a review paper should be research original papers.

I estimate that your question is, or will be, in the sphere of interest of almost every researcher. Personally, I accept that the scientific interest in a scientific report should include all (if possible) articles covering the area in which the research report is attempted to be designed (of any form) including a review of the literature. As one of the possible answers to your dilemma, you try to ask yourself this question in the form of a contraposition. If You not cited (almost) all the scientific reports related to the chosen phenomenon for observation, then is your report a comprehensive review article?

You can look at your dilemma within the domain of 'ethics of scientific correctness'. How will you feel when, in the near future, another researcher, in an effort to overestimate the paradigm of the observed phenomenon within that chosen scientific domain, omits this Yours report? Will you, politely speaking, feel neglected?

I would like to extend my gratitude to all four of you, for solving my doubt. You all have not only helped me but other researchers as well. Thank You!

In bibliometric analysis, while conducting performance analysis and science mapping/network analysis, should we consider review papers?

Yes, considering review articles in analysis when writing bibliometric review papers helps us in analyzing any trends in the data obtained. It might take a lot of time, but the analysis results are much better...

sure, one should consider a review paper while performing bibliometric analysis, In most cases, review papers received the highest average citation per publication as compared to article and other forms of documents.
