A study is conducted to estimate survival in patients following kidney transplant. Key factors that adversely affect success of the transplant include advanced age and diabetes. This study involves 25 participants who are 65 years of age and older and all have diabetes. Following transplant, each participant is following for up to 10 years. the following are times to death, in years, or the time to last contact (at which time the participants was known to be alive). Deaths: 1.2, 2.5, 4.3, 5.6. 6.7, 7.3 and 8.1 years Alive: 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 years Interval in Years Number At Risk During Interval, Nt Average Number At Risk During Interval, Nt*=Nt-Ct/2 Number of Deaths During Interval, Dt Lost to Follow-Up, Ct Proportion Dying qt = Dt/Nt* Proportion Surviving pt = 1-qt Survival Probability St = pt*St-1 0-2 2-4 4-6 6-8 8-10 Use the Kaplan-Meier approach to estimate the survival function. Referring to the graph below: What is the probability of surviving 6.5 years? A. None B. 0.85 C. 0.60 D. 0.90 Patients have an 85% chance of surviving how many years? A. 6.0 B. 4.25 C. 3.2 D. 5.5 Time, Complete the table below Years Number at Risk Nt Number of Deaths Dt Numbers Censored Ct Survival Probability St+1= St*((Nt-Dt)/Nt) 0 25 1.2 2.5 3.4 4.1 4.2 4.3 5.6 5.7 5.9 6.3 6.4 6.5 6.7 7.3 8.1 8.2 8.6 8.9 9.4 9.5 10.0 Interval in Years Number At Risk During Interval, Nt Average Number At Risk During Interval, Nt*=Nt-Ct/2 Number of Deaths During Interval, Dt Lost to Follow-Up, Ct Proportion Dying qt = Dt/Nt* Proportion Surviving pt = 1-qt Survival Probability St = pt*St-1 0-2 2-4 4-6 6-8 8-10 Solution Probability of surviving 6.5 years: A. None of the above 85% chance of surviving: B. 4.25 years.

A study is conducted in patients with HIV. The primary outcome is CD4 cell count which is a measure of the stage of the disease. Lower CD4 counts are associated with more advanced disease. The investigators are interested in the association between vitamin and mineral supplements and CD4 count. A multiple regression analysis is performed relating CD4 count to use of supplements (coded as 1=yes, 0=no) and to duration of HIV, in years (i.e., the number of years between the diagnosis of HIV and the study date). For the analysis, Y=CD4 count. = 501.41 + 12.67 Supplements %u2013 30.23 Duration of HIV A. What is the expected CD4 count for a patient taking supplements who has had HIV for 2.5 years? = ________ B. What is the expected CD4 count for a patient not taking supplements who was diagnosed with HIV at study enrollment? = ________ C. What is the expected CD4 count for a patient not taking supplements who has had HIV for 2.5 years. = ________ Solution (a) 501.41 + 12.67*1+30.23*2.5 =589.655 (b) 501.41 + 12.67*0+30.23*1 =531.64 (c) 501.41 + 12.67*0+30.23*2.5 =576.985.

A student scored 50 percent on a test, and was in the 43rd percentile. Explain these two numbers. Solution I. The 50 percent means that the student correctly answered half of all of the questions asked on the test. Percent score is a way to compare objects against a set rubric. II. Scoring in the 43rd percentile means the student performed better than 43% of all test takers. Percentile is a way to compare objects against one another..
