Figure 3: First page of the CONSORT questionnaire. (A) Because reporting guidelines and checklists vary in length, only after the form loads can the interface indicate progress through the questionnaire. A user-friendly system would also include a way for users to jump to a specific question or page. (B) The help button to the right of each field could bring up the associated section of the CONSORT Explanation and Elaboration document. (C) An autocomplete field with a controlled vocabulary of the possible sections in a structured abstract, such as the one from the National Library of Medicine. (D) Required fields are indicated by an asterisk. (E) Users should be able to navigate to the next page without filling required fields in this particular page. Only at the end of the questionnaire will the system flag empty required fields. (F) Users should be able to save their progress at any time. Better yet, the system could autosave at regular intervals. (G) Users should also be able to exit at any point.
