Multiple logistic regression analysis for body composition parameters associated with treatment modificationa
| Parameter | Odds ratio (95% CI) | P‐value |
|---|---|---|
| Pretreatment | ||
| SMI (5 cm2/m2 increase) | 0.70 (0.48–1.03) | 0.07 |
| SMD (5 HU increase) | 0.70 (0.49–1.01) | 0.06 |
| TATI (5 cm2/m2 increase) | 0.98 (0.94–1.02) | 0.36 |
| SMG (100 AU increase) | 0.80 (0.69–0.93) | 0.004 |
AU, arbitrary unit; CI, confidence interval; SMD, skeletal muscle radiodensity; SMG, skeletal muscle gauge; SMI, skeletal muscle index; TATI, total adipose tissue index.
