Not reviewing the author guidelines before writing a manuscript for a particular journal.
Not following the author guidelines, for example, an original study may require a structured abstract, whereas a case report may require an unstructured abstract
References need to be cited in the ascending order, and a reference may be repeated once it has been cited.
Reference citation is also specific to a journal; for example, it can be  or  or (1) or 1
Figures should be of high quality at 300 dpi per square inch, also try to submit them in tiff format. Do not include figures in the word document until specified. The images have to be uploaded separately in the manuscript management system after the upload of word documents.
please refer to the author guidelines; otherwise, just see an old article from the same journal and see how the figure legend is written. A figure legend is also specific to every journal; some journals ask for age etc. These formats do not change with time.
Always hide the identity of the patient and obtain institutional review board permission when applicable.
Please list all the authors at the initial submission, do not ask for an author to be added after the manuscript is submitted- it sounds fishy.
The corresponding author should make sure that all authors included in the study have contributed significantly to the creation of the manuscript. To include a name if they have not contributed significantly is unethical.
When using a table or figure from another publication or even from your prior publication, due credit should be written under the table or figure.
Figures and tables published in open access journals should only be used after their permission.
Avoid plagiarism. Most manuscript systems use plagiarism detection tools.
The grammar and English should be appropriate; use a professional service to help you.
Always submit a cover letter as to why your manuscript is unique and deserves to be published.
If an open access journal charges an article processing fee commonly called APC, do not presume your manuscript will be accepted because you are paying a fee. The manuscript is peer-reviewed and accepted for publication if recommended by the reviewers. The money you pay is to cover the publication expenses as your manuscript is free to all the readers worldwide. For any questions or concerns please write to firstname.lastname@example.org
