Guide for Authors
Clinical Nutrition, an official journal of ESPEN, The European Society for Clinical Nutrition and Metabolism, is an international journal providing scientific information on nutritional and metabolic care and the relationship between nutrition and disease both in the setting of basic science and clinical practice. Published bi-monthly, each issue combines original articles, reviews and other types of publications that will provide an invaluable reference for any specialist concerned with the field of interest.
Nutrition and nutritional care have gained wide clinical and scientific interest during the past decades. The increasing knowledge of metabolic disturbances and nutritional assessment in chronic and acute diseases has stimulated rapid advances in design, development and clinical application of nutritional support. The aims of ESPEN are to encourage the rapid diffusion of knowledge and its application in the field of clinical nutrition and metabolism.
Being an journal of ESPEN with members having various interest fields, either focused on basic research or clinical disciplines, the journal reflects the scientific nature of this multidisciplinary background and encourages the coordination of investigation and research from these disciplines. The journal publishes guidelines, consensus statements, review papers, original articles, short communications, and letters to the editor on those factors in acute and chronic diseases, which have metabolic and nutritional implications. It also publishes scientific works related to the development of new techniques and their application in the field of clinical nutrition.
The e-SPEN Journal is an electronic-only official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN). Published bimonthly, the e-SPEN Journal focuses on publishing articles on the relationship between nutrition and disease in the setting of basic science and clinical practice. e-SPEN Journal is available to all members of ESPEN and to all subscribers of Clinical Nutrition. Should the Editor-in-Chief feel that a paper which has been submitted to Clinical Nutrition is more suitable for publication in the e-SPEN Journal, the author will be advised by the Editorial Office and will then have the choice whether to proceed with publishing their paper in the e-SPEN Journal or to withdraw their paper. Manuscript submission directly to the e-SPEN Journal should be clearly indicated in the covering letter.GENERAL INFO ABOUT MANUSCRIPT SUBMISSIONS

Manuscript preparation and format. . Full instructions for manuscript submission are on http://help.elsevier.com/app/answers/detail/a_id/116/p/7923. Please follow these guidelines. A checklist for submitting manuscripts is available during submission on the Attach Files page. A PDF proof is generated from the uploaded files and this is then used for reviewing. Please note that even though manuscript source files are converted to PDF at submission for the review process, the source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revisions, will be managed via this system, and authors will also be notified via e-mail, removing the need for a hard-copy paper trail.Manuscripts may be submitted from any country and must be written in clear, concise English. When the editorial board feels that the English language needs to be improved, you should seek help from professional language support.
Manuscripts should be double-spaced (including references, tables, and figure legends).

Clinical Nutrition and e-SPEN Journal have adopted the proposal from the International Committee of Medical Journal Editors (ICMJE) which require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Clinical trials are defined as "biomedical or health related studies in human beings that follow a defined protocol." In addition to intervention studies, this definition encompasses observational, prevention, quality of life, diagnostic, and screening trials (www.clinicaltrials.gov). Any clinical trial for which subject recruitment began after July 1, 2008 must be registered in one of the five ICMJE-approved public trials registries (i.e.,www.clinicaltrials.gov, www.isrctn.org, www.umin.ac.jp, www.trialregister.nl). Is this study appropriately registered? If so, please report the study ID number and the website where the clinical trial is registered on the title page of the paper. If the study is not registered, authors must do so before the submitted paper will be considered for peer-review. If the study began before July 1, 2008, the initial recruitment date should be reported in the appropriate place in the Materials Methods section. Clinical Nutrition and e-SPEN Journal require prospective registration of all trials.Report. Should not contain more than 30 references and organized as Full Length Articles and are submitted by chairs of Special Interest Groups (SIG) or are submitted in collaboration with the Editorial Office.
Meta-analyses. Should not contain more than 50 references and organized as Full Length Articles. All Meta-analyses submitted for publication in Clinical Nutrition and e-SPEN Journal should also include a completed uploaded PRISMA Statement. We have adopted the definitions of systematic review and meta-analysis used by the Cochrane Collaboration. A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyze data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyze and summarize the results of the included studies. Meta-analysis refers to the use of statistical techniques in a systematic review to integrate the results of included studies. Downloadable forms are located at http://www.prisma-statement.org/statement.htm.MORE DETAILED INFORMATION ABOUT THE SECTIONS IN THE MANUSCRIPTTitle Page.
