Question

A hypothetical study was conducted with 20 participants to investigate the 2-year survival probability of persons diagnosed with liver cancer. Kaplan-Meier survival estimates resulted in the table below: Time (months) Individuals at Risk Number of Events Conditional Probability of Event Conditional Probability of Survival Cumulative Probability of Survival 4 20 1 1/20=0.050 19/20=0.950 (A) 6 19 1 1/19=0.053 18/19=0.947 0.900 10 16 1 1/16=0.063 15/16=0.938 0.844 12 15 1 (B) 14/15=0.933 0.788 19 12 1 1/12=0.083 (C) 0.722 21 10 1 1/10=0.100 9/10=0.900 0.650 24 8 1 1/8=0.125 7/8=0.875 0.569 (D) What is the best interpretation of the value in the cell labeled (D)? Group of answer choices 57% of persons who survived to 21 months also survived to 24 months. The Kaplan-Meier survival function for this study is estimated to be .125. The probability of surviving 24 months given survival to 21 months is 57%. The probability of surviving beyond 24 months for participants in the study is 57%.
