Change of body composition parameters during treatment
| Variable | First CT scan | Second CT scan | Absolute change per 180 days | Relative change per 180 days (%) | ||||
|---|---|---|---|---|---|---|---|---|
| Mean ± SD | Mean ± SD | Mean | 95% CI | P‐value | Mean | 95% CI | P‐value | |
| BMI (kg/m2) | 22.3 ± 3.4 | 23.2 ± 3.3 | 0.8 | 0.6 to 1.1 | <0.001 | 4.1 | 2.9 to 5.3 | <0.001 |
| SMI (cm2/m2) | 41.9 ± 7.0 | 41.1 ± 7.5 | −0.7 | −1.3 to −0.2 | 0.005 | −1.8 | −3.1 to −0.4 | 0.01 |
| SMD (HU) | 38.0 ± 7.3 | 37.2 ± 7.3 | −0.8 | −1.4 to −0.2 | 0.009 | −1.7 | −3.3 to −0.03 | 0.046 |
| TATI (cm2/m2) | 88.3 ± 44.8 | 95.3 ± 43.6 | 6.7 | 3.2 to 10.2 | <0.001 | 15.0 | 9.2 to 20.8 | <0.001 |
Bolded P‐values are those significant with a P < 0.05. BMI, body mass index; CI, confidence interval; CT, computed tomography; HU, Hounsfield unit; SD, standard deviation; SMD, skeletal muscle radiodensity; SMI, skeletal muscle index; TATI, total adipose tissue index.
