Results
A total of 24 patients were included in the data analysis.
Body composition analysis,
including patient preparation,
was completed in 90 seconds or less.
Median age was 56.5 years (range: 30-87),
62% of the patients were male.
The median weight was 95 kg (range: 58-151).
Median BMI was 31.3 kg/m2 (range: 19.5-47.6).
Median LBM with the BIA device was 68.7 kg (interquartile range (IQR): 46.3-84.2).
Median LBM using the Boer formula was 65.4 kg (IQR: 48.4-81.7).
Median LBM using the James formula was 66.6 kg (IQR: 46.4-78.7).
Median LBM using the Hume formula was 61.4 kg (IQR: 46.8-74.9).
Median %LBM BIA 71.5% (IQR: 61.1-78),
median %LBM Boer formula 68.2% (IQR: 57-80),
median %LBM James formula 68.8% (IQR: 55.7-77.7),
median %LBM Hume formula 63% (IQR: 56.8-76).
The results are summarized in table 1.
A simple scatter plot showing the distribution of LBM-estimates using the three formulas and BIA is shown in figure 3.
The correlation coefficients for LBM between the BIA and the three formulas (Boer,
James,
Hume) were 0.95 (p<0.001),
0.93 (p<0.001) and 0.95 (p<0.001) respectively.
