• The measure must correlate with risk of the outcome in patients without a given medical intervention. |
• The measure must continue to correlate with risk of the outcome after modulation with a given therapy. |
• Therapeutically modulated levels of the measure must predict the net effect of the treatment on the clinical outcome. |
• The correlation between therapeutically modulated levels of the measure and risk of outcome must be consistent across various classes of interventions and population subsets. |
