Assume that we have 10 main articles in our research area of interest and we want to compare between them by using a comparative method or technique
Hi Madi, maybe you can use meta-analysis to evaluate your 10 articles. Good luck
Hi Tamer.
What sounds like a simple question is actually quite complicated. It very much depends on what types of studies the articles are based on, that is, quantitative, qualitative, mixed methods, and if quantitative, RCT or observational. Each one should first be assessed for quality using one of the numerous check lists available (eg CASP). There are many different ways of comparing or aggregating the results from the studies ranging from a full Cochrane review with meta-analysis to a scoping study.
In the first instance, have a look at the Cochrane and PEDRO websites.
Hi Mady, you can consult:
Ragin, Charles C. (1987) The Comparative Method. Moving Beyond Qualitative and Quantitative Strategies. Berkeley: University of California Press. Ragin, Charles C. y Helen M. Giesel.

I agree with Adrian that a great deal depends on the methodological diversity of the studies. If they are relatively similar in that regard, then I like the idea that several people have suggested of using the papers as "cases" in a systematic case study.
You could think of this as creating something like a matrix, where the rows are the 10 papers and the columns are the dimensions that you want to use as the basis for your comparison. That would help you systematically locate similarities and differences among the articles.
If all the papers have similar,@ I think that systematic sampling will be good.
