Table 2:
Cluster specific subject characteristics for the Fort Jackson and PBRC studies. Summary of body composition measures within each cluster for the PBRC cohort is provided. The high fat-low fat free mass group is associated with Cluster Number 3 while the low fat-high fat free mass group is associated with Cluster Number 4. Cluster Number 2 represents individuals with a higher BMI and lower % fat mass than Cluster Number 3. Cluster Number 1 is largely populated in both Fort Jackson and PBRC by females.
