Lymphocytic leukemia Assignment Help
An epidemiologist is interested to know the 10-year survival probability of children diagnosed with acute lymphocytic leukemia (ALL). The life table below represents 100,000 children who were diagnosed with ALL within the past year. Each interval in the life table represents the number of years followed. Use this life table below to answer the following questions.
|Life table of 100,000 children diagnosed with acute lymphocytic leukemia|
|Years of follow-up||Number at Risk||# of Deaths||# of Lost to Follow-up or Competing Causes (Censored)||Effective Number at Risk||Risk of Death||Survival Probability||Cumulative Survival Probability|
What is the effective number of children at risk for the first interval (0-5 years of follow-up)? Lymphocytic leukemia Assignment Help
What is the risk of death for the first interval?
