j-curve phenomenon


J-curve phenomenon refers to a pattern on a graph; in cardiovascular medicine, it plots a group of people's risk of death from cardiovascular disease based on blood pressure or blood cholesterol levels. Those with low blood pressure and/or cholesterol levels are less likely to die; the higher their blood pressure and/or cholesterol levels, the more likely they are. The J-shaped curve on the graph leads to the term J-curve phenomenon.
