Bioimpedance analysis results | All patients (n = 196) | Survivors (n = 166) | Non-survivors (n = 30) | p-value |
---|---|---|---|---|
Resistance (Ω) | 459 ± 92 | 455 ± 89 | 476 ± 108 | 0.26 |
Reactance (Ω) | 39.0 ± 11.3 | 39.8 ± 10.9 | 34.5 ± 12.7 | 0.02 |
Phase angle (°)a | 4.9 ± 1.3 | 5.0 ± 1.3 | 4.1 ± 1.2 | < 0.001 |
p-values depict the statistical difference between 90-day survivors and non-survivors: independent T-test, equal variances not assumed. a Phase angle = arc tangent of (Xc/R)*180°/π
