Dear Irum Abbasi

The journal “PLOS Medicine” is a highly reputed journal in the field of medicine. Their impact factor 2023 (15.8) is high. So, by itself it is a safe choice. However, I see a number of problems:

-I estimate that they only accept manuscripts with significant impact (and a certain degree of urgency)

-The fee is (ridiculously) high 6300 USD https://plos.org/publish/fees/

-Looking at what you said yourself (my study is ‘very simple’ and the results are limited) I think it is not worth the try since the chances of success are slim to none

I think you should either extent the study or go for a somewhat more modest approach. There are numerous journals out there that can serve your purpose (getting your first research results published). Go for example to SCImago https://www.scimagojr.com click on Journal rankings and select Medicine (and select further for example neurology) then you end up with numerous suggestions. Personally, I would scroll down to Q2 and further (and be sure there are more than enough journals which might not be high impact journals but are just fine and more than just fine).

Best regards.

PS. Take for example https://www.sciencedirect.com/journal/journal-of-the-neurological-sciences here you can choose the open access option (but with a pretty hefty fee) or decline this option and go for the so-called subscription-based option (which is just fine for a first publication published by a well-known publisher that a large majority of researcher can access through their institutional license).
