Statistical evaluation of prognostic factors in ALL and treatment results
Abstract:
Prognostic factor evaluation is a frequent and desirable investigative activity in clinical trials. Nevertheless, a number of errors in the evaluation of such factors occur quite commonly. Many of these problems are due to inappropriate statistical interpretation of the analyses that are conducted. A detailed discussion of several problem areas is given. In the area of childhood ALL trials, issues related to the appropriate choice of disease end-points for analysis of prognostic factors are discussed.
