This journal “Open Journal of Clinical and Medical Case Reports” is a so-called stand-alone journal which is mentioned in the Beall’s list (https://beallslist.net/standalone-journals/ ). This a red flag that this might be a predatory journal. This is an indication but there are more red flags that this journal is most likely predatory:
-Contact info looks questionable (does not seem to resemble a ‘real’ office)
-Impact factor claim is misleading. They are not indexed in Clarivate’s SCIE index (which can be checked here https://mjl.clarivate.com/home ) and therefor they have by definition no impact factor.
-In addition to the fake impact factor info they mention in their indexing info DRJI, a so-called misleading metric (https://www.jclinmedcasereports.com/indexing.html ) often used by predatory journals
-They use in their open access info (https://www.jclinmedcasereports.com/open-access.html ) large parts of the text from the following website (https://www.springernature.com/gp/open-research/about/the-fundamentals-of-open-access-and-open-research ) without proper reference. Compare:
“Open Access is the free of charge, instant, online availability of research articles, together with the rights to use these articles fully in the digital milieu.” With the original “Open access (OA) refers to the free, immediate, online availability of research outputs such as journal articles or books, combined with the rights to use these outputs fully in the digital environment”
