Manuscript Requirements
Journal Style
Clinical Therapeutics expects manuscripts to conform to the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals” (the Vancouver style; N Engl J Med. 1997;336:309–315 or www.icmje.org). Reports of randomized controlled trials should conform to the CONSORT guidelines (www.consort-statement.org). A diagram illustrating the flow of participants through the trial is required. A copy of our tips for authors is available on request.
All manuscripts should be typed double-spaced, with the pages numbered. The title of the paper, followed by the full names of the authors; their highest academic degrees (eg, MD) and professional affiliation; and the complete contact information, including mailing address, phone, fax, and e-mail address of the corresponding author, should appear on the title page only. If any material contained in the manuscript has been presented at a meeting, the full name, location, and inclusive dates of the meeting should appear on the title page; this information will be published if the article is accepted. A sponsored database would classify as a clinical trials registry, which would not be considered duplicate publication. Posting in this database does not exclude publication in the journal. We would request, however, that mention be made to the posting in the manuscript and the registry number of the posting should be included after the abstract.
Language Services
Authors who require information about language editing and copyediting services pre-submission, please visit http://www.elsevier.com/locate/languagepolishing for more information. Please note Elsevier neither endorses nor takes responsibility for any products, goods, or services offered by outside vendors through our services or in any advertising. For more information, please refer to our Terms & Conditions.
Authorship
As stated in the Uniform Requirements (see above), credit for authorship requires substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; drafting of the manuscript or critical revision for important intellectual content; and final approval of the version to be published. At time of submission, Clinical Therapeutics requires all authors to sign a statement that he or she accepts full responsibility for the conduct of the trial, had access to the data, and controlled the decision to publish. Each author of a review article must sign a statement that he or she approved the search terms, article selection, and manuscript outline, and accepts full responsibility for all conclusions drawn. Any change in authorship after submission must be approved in writing by all authors.
Financial Disclosure
Authors are required to disclose, in writing, any financial interests (eg, employment, consultancies, stock ownership or options other than mutual funds, honoraria, expert testimony) in the materials or subject matter dealt with in the manuscript. (Please consult the Uniform Requirements.) The information on this form may be published at the discretion of the Editor-in-Chief.

Prospective, Observational, or Interventional Postmarketing Studies
Postmarketing studies must undergo review by an institutional review board (IRB) or ethics committee. Patients must give written informed consent unless a waiver of consent is allowed by the IRB. Patients must be informed of any real or potential conflicts of interest, including compensation of the investigator and potential costs to the patient that may result from their participation in the study. The amount of the remuneration of the investigators for their participation in postmarketing studies must be approved by the IRB/ethics committee. If the design of a prospective postmarketing study calls for a treatment intervention such as a switch or withdrawal, then criteria must be established a priori for patient selection, the implementation of the intervention, and assessment of success/failure of such intervention. Such criteria must be scientifically justified, documented, uniformly applied and enforced, and clearly reported in the study report. Additionally, the patient or his/her insurance provider will not be required to pay for costs related to prospective interventions such as those that may result from a drug switch or withdrawal.
These criteria do not apply to retrospective observational studies, such as chart reviews, postmarketing safety surveillance studies, or government-mandated Phase IV trials.
Review Articles
Comprehensive reviews and meta-analyses of the literature are welcomed. Authors should contact one of the editors to discuss the topic area to avoid duplication with previously submitted or accepted manuscripts. For more information about what constitutes a good review see CP Mulrow (The medical review article: State of the science. Ann Intern Med 1987;106:485-488) and AD Oxman et al. (User’s guide to the medical literature. VI. How to use an overview. Evidence-based medicine working group. JAMA 1994;272:1367-1371).
The review should include an accurate, succinct title; a structured abstract; an introduction that specifies the purpose of the review; methods section that identifies the databases that were searched, search terms used, and inclusion/exclusion criteria for identified articles; an assessment of the validity of reviewed studies; and a summary that includes future directions for studies in this area.

Consensus Statements
These papers are guidelines developed by an independent panel of experts within the stated specialty and are based on the current state of knowledge in that area. The submission should include an unstructured abstract; an introduction clearly describing the objective, member selection, and development of the panel; details of how opinions were formalized (including how disagreements were addressed); a fully-referenced description of each recommendation; a comprehensive conclusion; acknowledgment of financial and editorial support including detailed conflict of interest statements from all parties involved in the panel and manuscript creation; and references.

Commentaries
These papers address an important issue in clinical medicine, health policy, or medical research in a thorough, well-referenced, systematic or evidence-based manner. The submission should include a structured abstract, an introduction, pertinent information detailing the position of the paper, a discussion, a conclusion, and references.

Case Reports
New or unusual events in one or more patients that provide significant information about adverse drug reactions, drug-drug interactions or drug-disease interactions. The types of case reports generally include unique cases, unexpected associations, or unexpected events. Data regarding suspected adverse drug reactions should provide a description of the event, details regarding the implicated medication (purpose, when initiated), previous adverse drug reactions with similar drugs, effects of dechallenge or rechallenge, and treatment for the reaction. Please do not submit cases purporting to establish drug efficacy. The report should be factual, concise, logically organized, and clearly presented. In the case of adverse drug events, please use the Naranjo ADR probability scale to determine the likelihood that the events were drug-related (Naranjo CA, et al. A method for estimating the probability of adverse drug reactions. Clin Pharmacol Ther 1981;30:239-245).
The report should include an accurate, succinct title, a structured abstract, an introduction, case description, discussion, conclusions, and references. A table or figure may be included. The introduction should announce the subject and purpose of the report, including statements of why the case is important and how the literature search was performed. The case description should include a narrative account of the case with brief, pertinent clinical, laboratory and medication information. The discussion should comment on evidence that the case is new or unusual and consider possible alternative explanations for case features. The conclusion should provide a summary of the adverse drug reaction-medication relationship, how to treat it, and how to avoid it.
For more information about what constitutes a good case report, see Vandenbrouke JP, In defense of case reports and case series. Ann Intern Med 2001;134:330-334 and DeBakey L and DeBakey S, The case report. I. Guidelines for preparation. Int J Cardiol 1983;4:357-364.
