The study investigated the relationship between cholesterol levels and death rates. The study included 4,553 Pima Indians aged 20 or over who were followed for more than 12 years.
After analysing 12 years of data the researchers found that those with the lowest cholesterol had a 9% increase in death rates compared to those with the highest cholesterol.
