Information for authors

www.thelancet.com November 2019 How to submit your paper Manuscript submission Manuscript submission to all Lancet journals is free. Payment of article processing fees is made after acceptance (see later). Manuscripts should be submitted online via the The Lancet Global Health’s online submission and peer review website (known as EM) at www.editorialmanager.com/langlh • Simply log on to EM and follow the on-screen instructions for all submissions • If you have not used EM before, you will need to register first. In EM, the corresponding author is the person who enters the manuscript details and uploads the submission files • Inclusion of illustrations (eg, photographs, graphs, diagrams) is a prerequisite for many publication types. Submission of original and editable artwork files is encouraged. Digital photography files should have a resolution of at least 300 dpi and be at least 107 mm wide. Before and after images should be taken with the same intensity, direction, and colour of light. • In almost all cases, if you have a finished manuscript, you should submit it, rather than contacting The Lancet Global Health to enquire whether an unseen manuscript is likely to be accepted. Unless you have been asked by the Editor to submit by email, you should use the online system for all types of submission, including Correspondence • If you have any technical problems or questions, please contact our dedicated customer support: For the Americas: +1 888 8347287 (09:00 to 17:00 central standard time) For Asia and Pacific: +81 3 55615032 (09:30 to 17:30 Japan standard time) For Europe and rest of the world: +44 1865 843577 (08:30 to 17:00 GMT) For Chinese-speaking customers: +86 10 85208780 (9:00 to 17:30 China standard time) For Spanish-speaking customers: +34 932 406176 (09:00 to 17:00 GMT) For French-speaking customers: +33 171 165608 (09:00 to 17:00 GMT) Email: globalhealth@lancet.com
