In fact, smoking had been advertised as "healthy" for many years, and there had been no clear explanation why rates of lung cancer had soared. To further investigate the link, the Medical Research Council (MRC) instructed its ''Statistical Research Unit'' (later the Oxford-based ''Clinical Trial Service Unit'') to conduct a prospective study into the link. This approach to medical questions was fairly new: in the 1954 "Preliminary report", the researchers felt it necessary to offer a definition of the ''prospective'' principle. The study, when it was published in 1956, heralded a new type of scientific research, showed the relevance of epidemiology and medical statistics in questions of public health, and vitally linked tobacco smoking to a number of serious diseases. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British Doctors Study」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
