-Relevance of the research topic: First, it is necessary to determine whether the cited literature is relevant to the research topic. If the document has nothing to do with the research topic or has no substantial contribution to the research results, it should be avoided.
-Quality of documents: Secondly, we need to consider the quality of documents. High-quality literature usually has high credibility and authority, so it should be cited first in medical papers.
-the author's reputation: the author's reputation is also an important factor in judging the literary value. If the author has a high reputation and influence in this field, then his published literature is more valuable.
-Publication time and citation times: In addition, the publication time and citation times of the literature need to be considered. Generally speaking, the documents published earlier and widely cited are more authoritative, so they are more worthy of being cited.
In a word, to judge which documents in medical papers are worth citing, many factors need to be considered comprehensively, including the relevance of research topics, the quality of documents, the reputation of authors, the time of publication, the number of citations and so on. At the same time, we should also pay attention to abide by the relevant academic norms and moral standards to ensure that the cited literature sources are reliable, authentic and credible.
