The chief investigator will be responsible for preparing a final report of the trial which should be provided to the sponsor, the ethics review board, and any other authorities determined by local legislation. The final report is a comprehensive description of the study after its completion including a presentation and evaluation of the results, statistical analyses and a critical ethical, statistical and clinical appraisal. The results of the clinical research conducted on acupuncture should be published in a timely fashion and must include all adverse events. Even studies which fail to demonstrate effectiveness should be published, as selective publication, showing only results that are favourable, will only lead to a form of misconception known as publication bias.
