IJPT Author Guidelines


Authorship

Authorship is determined if all three of the following conditions have been met from the ICMJE Uniform Requirements for Manuscripts:

  1. Substantial contributions to study conception and design, acquisition of data, or analysis and interpretation of data
  2. Drafting the article or revising it critically for important intellectual content
  3. Final approval of the version to be published

Any contributors to the manuscript who do not meet all three criteria above are not authors but should be included in the Acknowledgements section.


Conflicts of Interest

Authors are responsible for disclosing any financial or personal relationships that may bias their work. Authors should state explicitly if they do or do not have any potential conflicts of interest on the title page of the manuscript. Each author is also required to state conflicts of interest through the manuscript submission process online. A fillable PDF is available at www.icmje.org. Or, the authors can state their conflicts of interest in the manuscript.

View our Editorial Board Conflict of Interest Policy and Conflict of Interest Disclosures here.


Copyright/Open Access

Articles published in IJPT are open access and are distributed under the Creative Commons Attribution license (CC-BY). We will publish the following note on the title page of each article:

"Distributed under Creative Commons CC-BY"

IJPT is an open access journal and does not charge the author for submission or publication fees.


Data Timeliness

Data from more than five years ago will receive lower priority for publication. However, authors can provide a detailed justification on why the data is still relevant today


Data Sharing Policy

In keeping with the recommendations of the ICMJE, reports on randomized clinical trials must indicate how data are shared. Authors must provide a Data Sharing Statement on the title page of the submitted manuscript. For statement examples and specifics, please refer to the ICMJE's data sharing statement policy here.


Electronic Submission

Manuscript submissions are done electronically through the Editorial Manager site. There is no submission fee. The corresponding author is the primary correspondent during the submission and review process. After submission, the corresponding author will receive a confirmation email that includes the manuscript"s number. All decisions will be sent via email. There are four possible decisions:

  • Rejection: the manuscript is questionable in its importance and impact to particle therapy, the originality of the work, the quality of the study, and its priority to the IJPT and its readership
  • Major revision: the manuscript contains information of potential importance but editors have a number of major issues raised; the IJPT is willing to reconsider the manuscript if the author addresses these major concerns, but cannot guarantee acceptance
  • Minor revision: editors find the manuscript potentially acceptable for publication if authors make some minor adjustments
  • Acceptance: editors have selected the manuscript for publication

The corresponding author is also responsible for reviewing and editing proofs if the manuscript is accepted for publication. There are no publication fees.


Embargo

Authors should not disclose the fact that their manuscript has been accepted to anyone, except coauthors and contributors, until it is published, without permission of the editors.


Ethics and Publication

IJPT enforces strict ethical policies and standards during the review process. We use iThenticate to check submissions against previous publications to verify the originality of submissions to our journal. We take issues in ethical publishing very seriously and our staff and editors have a zero tolerance policy in cases of plagiarism, data falsification, inappropriate authorship, and other similar issues.

We will not accept for review any manuscript that is currently under review at another journal. Submissions will not be accepted if it has previously appeared in any other publications. The only exception is if the work has been presented as an abstract at a conference, in which case, authors must state on the title page where and when the work was presented. 


Ethnicity/Race Reporting

If race/ethnicity is reported in the study, explain why it was assessed.  Indicate who classified individuals as to race/ethnicity, the classifications, and whether the options were defined by investigators or participants.


Funding - NIH Grants

IJPT is a Method D submission journal, meaning we will deposit the final peer-reviewed manuscript into the NIH Manuscript Submission System. We will start the deposit process. The authors and NIH awardees must approve the paper for processing and approve the paper for PubMed Central display.


Human and Animal Experimentation

  • Human subject anonymity
    • Manuscripts that are reporting data from studies involving human participants are required to be reviewed by an appropriate institutional review board or ethics committee, and a statement that the study was reviewed by such a board should be included in the Material and Methods section. Those without a formal ethics committee should follow the Declaration of Helsinki.
  • Non-cruel animal experimentation

Informed Consent and Patient Details

Studies on patients, research subjects or individuals require ethics committee approval and informed consent, which should be documented in your submission.

If including case details or other personal information or images of patients and any other individuals, related consents, permissions and releases must be obtained. Written consents must be retained by the author; the author must provide copies of the consents or evidence that such consents have been obtained only if specifically requested by the IJPT. All elements of dates (except year) that are directly related to an individual, including admission date, discharge date, death date, and all ages over 89 and all elements of dates (including year) indicative of such age, except that such ages and elements may be aggregated into a single category of age 90 or older, should NOT be used.  Read more about the HIPAA Privacy Rule here.

For more information, please review the IJPT Informed Consent Policy.


Manuscript Preparation and Style

Editing – Manuscripts submitted to the IJPT should follow the AMA Manual of Style, 10th Edition and/or Uniform Requirements for Manuscripts Submitted to Biomedical Journals. The editors reserve the privilege of editing manuscripts to conform with the stylistic conventions established in recent volumes of the IJPT, in these author guidelines, and in AMA Manual of Style, the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, as well as current terminology and accepted usage and practice.

  • Abbreviations – Avoid using abbreviations in the title unless space considerations require an exception. Abbreviations should be expanded at first mention in the abstract and in the body of the text.
  • Units of Measure – The metric system is preferred for the expression of length, area, mass, and volume. Temperature should be in degrees Celsius.
  • Names of Drugs, Devices, and Other Products – Use the generic names of products unless the specific trade name of the drug is essential for discussion.

Article Types
  • Original articles, Reviews, and Technical Reports should have a maximum of 4,500 words (including the abstract, body text, and figure legend).
  • Case Reports should have a maximum of 1,500 words.
  • Letters to the Editor, or Scientific Letters, do not require abstracts and should have a maximum of 3,500 words.
  • Technical Notes - Authors are welcome to write a technical note. This note will not necessarily be "academic," but it will contain practical advice for the mechanical, electrical, or dose-planning aspects of particle treatment. Technical notes should have a maximum of 3,500 words (including the abstract, body text, and figure legend).

Cover Letter

The cover letter should be an introduction of the manuscript to the Editor-in-Chief. It can summarize the purpose and intent of the manuscript, also emphasizing its relevance to particle therapy today.
