Below you will find some examples of study designs, please select the correct design for each example. The relation between total fiber intake and colon cancer was studied in 35492 male participants. Fiber intake was measured via food frequency questionnaires at the beginning of the study in 1988 and every two years thereafter prior to an endoscopic procedure to assess colon cancer. Between 1988 and 2006, 2099 colon cancer cases occurred. Occurrence of colon cancer was 39% higher in people with the lowest fiber intake as compared with people with the highest fiber intake. The study suggests that low intakes of fiber in men is associated with an increased risk of colon cancer. The study design is a:
