The object of the study was to evaluate the impact of high density lipoprotein (HDL) cholesterol on death rates in older people. The two year study analyzed HDL cholesterol data from 359 subjects aged 80 years and older.

The study found:
(a) The HDL cholesterol levels of men that died was 36.7 mg/dL (.9 mmol/l), whereas the HDL cholesterol levels in the men who survived was 43.3 mg/dL (1.1 mmol/l).
(b) The HDL cholesterol levels of women that died was 42.2 mg/dL (1.1 mmol/l), whereas the HDL cholesterol levels in the women who survived was 49.3 mg/dL (1.3 mmol/l).

The results of this study show that high levels of HDL cholesterol are associated with better survival in people aged over 80.

An analysis of 27 trials found the best way to raise HDL cholesterol is to eat saturated fat. See here.
