Trunk-to-Limb Fat Mass Ratio: Females, Age 85+

What these numbers mean

A value around 0.954 is typical (50th percentile) for women in this age group. The middle 50% of the reference population fall between about 0.787 and 1.115; values below or above that central range sit in the lower or upper half of the distribution.

These are percentiles for all US adults aged 20 and over, from NHANES 1999-2004 Hologic DXA scans. Values from another scanner brand or calibration are not directly comparable, and percentile position is not a clinical category.
