The table presents data on cholesterol levels (chol), age, and body mass index (BMI) for various individuals. The data columns are organized as follows:

- **chol (Cholesterol Levels)**: Indicates the cholesterol level in mmol/L. Values range from 4.46 to 9.27.

- **age**: Represents the age of the individuals. Ages range from 30 to 76 years.

- **bmi (Body Mass Index)**: Shows the BMI values for the individuals, ranging from 18.9 to 29.2.

**Data Entries**:

1. Chol: 5.94, Age: 52, BMI: 20.7
