Prediction of mortality by uni- and multivariate Cox-proportion analyses in the patients available for CT after 6 months (n = 119).
| Predictor | HR | 95% CI | P-value |
|---|---|---|---|
| Univariate analysis | |||
| Age | 0.994 | 0.964–1.028 | 0.749 |
| Sex, female | 0.602 | 0.263–1.203 | 0.185 |
| Relative decline in body mass index, % | 1.084 | 1.037–1.128 | <0.001 |
| Relative decline in FVC, % predicted | 1.041 | 1.013–1.069 | 0.004 |
| Relative decline in DLCO, % predicted* | 1.013 | 0.991–1.034 | 0.248 |
| Relative decline in ESMCSA, % | 1.057 | 1.027–1.086 | <0.001 |
| Multivariate analysis | |||
| Relative decline in body mass index, % | 1.036 | 0.986–1.088 | 0.163 |
| Relative decline in FVC, % predicted | 1.021 | 0.992–1.050 | 0.155 |
| Relative decline in ESMCSA, % | 1.039 | 1.007–1.071 | 0.015 |
Abbreviations: HR, hazard ratio; CI, confidence interval; FVC, forced vital capacity; DLCO, diffuse capacity of the lung for carbon monoxide; ESMCSA, cross-sectional area of erector spinae muscles.
*We analysed using n = 114, because 5 cases were missing.
