cut point

In an analysis of data, a specified value used to sort continuous variables into discrete categories. It may be set according to its usefulness in predicting abnormal clinical events or arbitrarily.

Blood pressure measurements, for example, are continuous variables: in general, the higher one's pressure, the greater one's risk of congestive heart failure, kidney disease, myocardial infarction, or stroke. The analysis of blood pressure measurements has shown that the risk for these events climbs sharply as systolic blood pressures rise above 139 mm Hg. Therefore hypertension is defined by the cut point of 140 mm Hg, even though lower pressures may be harmful for some patients and higher pressures may be relatively well tolerated by a small number of other patients.
