*Geometric means (first row) and geometric standard deviations (second row).
**Number of subjects (number of specific body part loadings may deviate slightly).
^Not available because these body parts were not washed.
^^Unavailable because there were an insufficient number of loadings to calculate a plausible geometric standard deviation.
