Do optimal prognostic thresholds in continuous physiological variables really exist? Analysis of origin of apparent thresholds, with systematic review for peak oxygen consumption, ejection fraction and BNP.

Do optimal prognostic thresholds in continuous physiological variables really exist? Analysis of origin of apparent thresholds, with systematic review for peak oxygen consumption, ejection fraction and BNP.

<h4>Background</h4>Clinicians are sometimes advised to make decisions using thresholds in measured variables, derived from prognostic studies.<h4>Objectives</h4>We studied why there are conflicting apparently-optimal prognostic thresholds, for example in exercise peak oxygen...
