This isn’t a good journal and the author isn’t an MD. The journal barely has an impact factor. 10 or more is considered very good (extremely reliable). This journal has less than 2; that’s super abysmal. Again, there is a reason major journals (IF of much more than 10) don’t deal with this.
The Impact Factor for a journal is calculated by dividing the number of citations in a year by the total number of articles published in the two previous years. This journal is barely a footnote. For comparison, Nature, one of the best of the best, has an IF of 64.8.
Science is a conversation. This low number means that only one or two articles cited each paper from this entire journal in the last two years, even just in passing. It’s not part of the conversation, and hardly has a seat at the discussion table.
