Tables:  All tables should be created with the 'insert table' function of Microsoft Word. Tables in portrait fromat should fit within the page margin (2.54 cm or 1 inch). Tables that are in landscape format will be published as supplementary files. The tables should be cited in numerical order in the text in bold font (Table 1, Table 2 etc). Each table should have a table number and a descriptive title above the table. Explanations for abbreviations and levels of significance should be given at the bottom of the table as letters in superscript (for example a, b, c etc), not as symbols (for example @, # etc.). Insert table(s) immediately after the references.

Figures and figure legends: All illustrations are referred to as "Figures" and must be numbered consecutively in bold font, for example (Figure 1, Figure 2 etc). Photomicrographs should be high resolution TIFF images (minimum 300 dpi). After creating the images as high resolution TIFF images, use the 'insert picture' function of the Microsoft Word to insert figures at the end of the article immediately after the tables. Provide figure legends including figure number, a short title and description immediately below each image. Also upload the figures separately at 'step 4' of the submission process. Photomicrographs should have internal scale markers. Symbols, arrows, or letters used in photomicrographs should contrast with the background. Explain the internal scale and identify the method of staining in photomicrographs.

Quality check of images: Do not submit images that are less than 300 dpi. Also, do not submit without checking the quality of the images because it will cause significant delay in processing of the manuscript. Manuscripts will not be sent out to reviewers until good quality images are submitted. There is a simple way to check the quality of the images before submission. After preparing the images, insert them in a Microsoft Word document using the 'insert picture' function. Save the document as a pdf. A good quality image will be sharper and non-pixelated. Print the image to confirm. A poor quality image will be pixelated without sharp edges. It will look a blurred or an ‘out of focus’ image. 

Units: Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressure should be in millimeters of mercury.

Abbreviations and Symbols: Use only standard abbreviations. Avoid abbreviations in the title of the manuscript. The spelled-out abbreviation followed by the abbreviation in parenthesis should be used on first mention unless the abbreviation is a standard unit of measurement.

Review articles: The style, title page, abstracts, tables, references and quality of images are similar to the above guidelines. A review article can be between 3000 and 5000 words, excluding the abstract and references. Write an introduction, followed by contents under various subheadings. Do not number the headings. 

Case Reports: The style, title page, abstracts, tables, references and quality of images are similar to the above guidelines. Write the case report under four major headings – introduction, case report, discussion and conclusion. 

Introduction: Write an introduction that provides background information of the case report in light of the available literature. 

Case report: Describe the case in detail. This should be covered under three subheadings – initial presentation, management and outcome. 

Discussion: Write a comprehensive discussion, but ensure that this is not the repeat of the case. What is novel about this case? What are the advantages and disadvantages of the existing paradigm? How does your management strategy compare or contrast with standard of care? What strategies can be employed for better management? 

Conclusion: Summarize the take-home message both in terms of the topic and management.

Letter to editor: Comments about any of the published articles in JRENHEP can be submitted as letter to editor. The word limit is 1000, including abstract and references.

Title: The title should identify that it is a letter to editor and that is about a published article in JRENHEP.

Example title: Letter to editor regarding [insert the short title of the manuscript].

Abstract: Write an abstract, no more than 100 words. abstract.

Body: Write your comments as paragraphs without any headings.

Other guidelines are similar to ‘review articles’.

Editorials are upon invitation only. 

Plagiarism Check: We have partnered with CrossRef to use iThenticate to detect plagiarism. Plagiarism is presenting other people's work or ideas as your own without acknowledging the original source. However, iThenticate gives a 'similarity index', which is the word-by-word copying of materials from previously published literature. We use similarity index to make a decision. Even if the original source was cited, articles with more than 10% similarity index will be returned to the authors without peer review for re-writing. For articles with similarity index between 1-10%, we follow the guidelines of Committee on Publishing Ethics (COPE) on text recycling to make a decision.
