IDEAL, Insight into the Determination of Exceptional Aging and Longevity

Model 1 shows the beta-coefficient and p-value from a simple linear regression model assessing the relationship between IDEAL status and resting metabolic rate. Model 2 expands upon model 1 by adding age and sex to the model. Model 3 expands upon model 2 by adding variables to account for body composition.
