Univariate and multivariate analysis of prediction of FEV1%pred by time since lung transplantation, BMI and BIA parameters.
| Univariate | Multivariate | ||||
|---|---|---|---|---|---|
| r | p-value | Coefficient | SE | p-value | |
| (Intercept) | 30.0 | 17.6 | |||
| Time since LT | 0.19 | 0.149 | −0.01 | 0.05 | 0.837 |
| BMI | 0.35 | 0.007 | 0.74 | 0.85 | 0.382 |
| PA | 0.41 | 0.002 | 4.80 | 3.63 | 0.190 |
| TBW | 0.31 | 0.019 | 0.24 | 0.86 | 0.781 |
| FFM | 0.32 | 0.014 | −0.42 | 0.74 | 0.572 |
| ECM | −0.02 | 0.857 | 1.44 | 1.14 | 0.210 |
| BCM | 0.40 | 0.002 | −0.77 | 1.62 | 0.635 |
| FM | 0.12 | 0.351 | 0.22 | 0.17 | 0.198 |
| ECM/BCM | −0.39 | 0.002 | −8.98 | 3.56 | 0.014 |
After multivariate analysis by a linear mixed model only ECM/BCM remained a significant predictor of predicted forced expiratory volume in 1 second.
r: Spearman’s correlation coefficient; SE: standard error; LT: lung transplantation; BMI: body mass index; PA: phase angle; TBW: total body water; FFM: fat free mass; ECM: extracellular mass; BCM: body cell mass; FM: fat mass.
