A 2007 U. S. study by Fontana, Klein, and Holloszy compared a number of factors associated with heart disease and metabolic disorders such as diabetes and blood pressure. Three groups of 21 participants in this observational study were matched for age, gender and other characteristics. The subjects in the raw vegan diet group were sedentary and had been eating a low-calorie, low-protein vegan diet composed primarily of unprocessed and uncooked plant-derived foods for at least 2 years. The subjects in the endurance runners group ran an average of 48 miles per week for an average of 21 years. The subjects in the western diet group consisted of sedentary and non-obese subjects who ate a typical western diet (characterized by high intakes of red meat, sugary treats, high-fat foods, and refined grains). All subjects in the study were healthy adults. Results of this study were published in the American Journal of Clinical Nutrition in 2006. The researchers found that the western diet group was more likely to have borderline-high to high blood pressure compared to the raw vegan diet group. Furthermore, 50% of the western diet group had higher blood pressure than 75% of the endurance runners. Students in a statistics class were asked to summarize the results of the study. Which of the student statements is an appropriate summary? Check all that apply.
