Multiple linear regression analysis for associations of gender, weight z-score at term-corrected age, being a twin and being fed exclusively human milk at term-corrected age with fat-free mass at term-corrected age (R2 = 0.88, p < 0.0001).
| Model | Fat-Free Mass Content at Term-Corrected Age (g) | ||
|---|---|---|---|
| β | 95% Confidence Interval | p | |
| Intercept | 3098.2 | 3018.1; 3178.3 | <0.0001 |
| Male (yes vs. no) | 84.3 | 41.1; 127.4 | <0.0001 |
| Being a twin (no vs. yes) | 23.4 | −23.6; 70.4 | 0.32 |
| Weight z-score at term-corrected age | 355.0 | 332.8; 377.2 | <0.0001 |
| Mode of feeding at term-corrected age (being exclusively human milk fed vs. being exclusively formula fed) | −104.1 | −151.4; −56.7 | <0.0001 |
