PJ Hoy ! 3 attempts. (5 points) Keto Diets - Among several diets, ketogenic diets, which are very low in carbohydrates and usually high in fats and/or proteins, have gained considerable popularity in the last few decades. Results regarding the impact of such diets on cardiovascular risk factors are controversial, both in animals and humans, but some improvements obesity and Type 2 diabetes have been observed. A study seeks to compare the effect of ketogenic diets on patients having Type 2 diabetes. A total of 765 patients who were diagnosed with Type 2 diabetes were randomly assigned to two groups. 358 patients assigned to Group 1 received a ketogenic diet high in proteins and fats (14% of energy as carbohydrate (carbohydrate <50 g/d), 28% of energy as protein, and 58% of energy as fat (<10% saturated fat)and the remaining 407 patients in Group 2 received a high carbohydrate diet (53% of energy as carbohydrate, 17% of energy as protein, and 30% of energy as fat (<10% saturated fat)]. Both groups of patients had supervised aerobic and resistance exercise activities for an hour three days a week. The researcher who evaluated the patients over the study period (to assess whether there was a decrease in the patients' glycemic variability assessed with use of 48-h continuous glucose monitoring) did not know which patients' were receiving the ketogenic diet. The table below summarizes some of the study results. Use these results to answer the following questions. Round all answers to four decimal places. 358 Group Group 1 (Ketogenic Diet) Group 2 (Carb rich Diet) Total Decrease in glycemic variability No change in glycemic variability Total 259 99 272 135 407 531 234 765 1. What proportion of patients displayed a decrease in glycemic variability? 2. What proportion of patients who showed no change in glycemic variability were assigned to carbohydrate rich diet? 3. Given that a patient was assigned to the ketogenic diet group, what is the probability that the patient has undergone a decrease in glycemic variability?

Answer 1

An) The proportion of patients diplayed D a decrease in glycernic variability Total decrease in glycermic Variability Total S31 76.5 = 0.6941 2) Proportion of patients who showed no change in glyceomic variability were assigned to .. carbohydrate sich dict . - Group 2 (carbrich Dict) - Total of no change in glejcermic variability 135 234 -0.576923 3) The probability that undergone a decrease the patient has in glycermic Variability 259 358 =0.72346
