The study investigated the association of various cardiac related factors with death rates in the elderly. The study included 331 hospitalised elderly patients, (average age 87years) who were followed for 378 days.

Regarding cholesterol levels, the study found:
(a) Patients who died had 12% lower levels of low-density lipoprotein (LDL) cholesterol than patients who survived.
(b) Patients who died had 7% lower levels of high-density lipoprotein (HDL) cholesterol than patients who survived.

In this study, elderly patients who died had lower cholesterol levels than patients who survived.
