  1. Background mortality in clinical survival studies.

    Article - En anglais

    In long-term follow-up studies of survival after an initial event (eg, an operation) mortality from causes othe than the one under study obscures the results, especially in elderly patients.

    In the traditional approach to the calculation of expected mortality a fictitious cohort is drawn from the general population, being matched for age, sex, and calendar time at the time of the initial event.

    The membership of this cohort is then kept constant from the intitial event until the closing date of the study.

    The survival and mortality of this static cohort is then compared with that of the dynamic patient cohort to throw light on mortality from extraneous causes.
