Use the life table approach to estimate the survival

Use the life table approach to estimate the survival function. Use years intervals of0–2; 2–4;
1. A study is conducted to estimate survival in patients following kidney transplant. Key factors that adversely affect success of the transplant include advanced age anddiabetes. This study involves 25 participants who are 65 years of age and older and all have diabetes. Following transplant, each participant is followed for up to 10years. The following are times to death, in years, or the time to last contact (at which time the participant was known to be alive).Deaths: 1.2, 2.5, 4.3, 5.6, 6.7, 7.3 and 8.1 yearsAlive: 3.4, 4.1, 4.2, 5.7, 5.9, 6.3, 6.4, 6.5, 7.3, 8.2, 8.6, 8.9, 9.4, 9.5, 10, 10, 10, and 10 yearsUse the life table approach to estimate the survival function.

A clinical trial is conducted to evaluate the efficacy of a new drug for prevention of hypertension in patients with pre-hypertension (defined as systolic blood pressurebetween 120–139 mmHg or diastolic blood pressure between 80–89 mmHg). A total of 20 patients are randomized to receive the new drug or a currently available drugfor treatment of high blood pressure. Participants are followed for up to 12 months, and time to progression to hypertension is measured. The experiences of participantsin each arm of the trial are shown below.New Drug Currently Available DrugHypertensionFree of Hypertension HypertensionFree of Hypertension7 8 6 88 8 7 910 8 9 119 10 1111 11 121212Estimate the survival (time to progression to hypertension) functions for each treatment group using the Kaplan-Meier approach.New DrugComplete the table below.Currently Available DrugComplete the table below.10/9/2017 HLTH 501 – A study is conducted to estimate survival in patients following kidney transplant. – SKU 103749https://www.hometaskguru.com/question/view/103749/HLTH-501-A-study-is-conducted-to-estimate-survival-in-patients-following-kidney-transplant 3/3To answer the question as to whether or not there is a difference in time to progression, a Chi square statistic is computed. The critical value for rejection of the nullhypothesis is 3.84. The computed Chi square is 0.335.Based on comparing the computed Chi square and the critical Chi square, which of the following is (are) true?A. There is not statistically significant evidence to show that thetime to progression is different between groups.B. There is statistically significant evidence to show that thetime to progression is different between groups.C. The time to progression is essentially the same for each group.D. a and c.The hazard ratio risk of progression to hypertension is 0.658. Based on this computation, which of the following is (are) true?A. The risk of progression to hypertension is reduced by 34.2% in patients assigned to the new drug as compared to the currently available drug.B. The risk of progression to hypertension is 1.52 times higher in patient’s current drug as compared to the new drug.C. The risk of progression to hypertension is 5.12 times higher in patient’s current drug as compared to the new drugD. a and b
