Association between mortality and psoas muscle-based variables.
| Variable | Studies, n | Summary HR (95% CI) | I2 |
|---|---|---|---|
| PMI (continuous variable) | 5 | 0.88 (0.77-0.99) | 81.4% |
| TPMT (continuous variable) | 4 | 0.92 (0.86-0.98) | 0% |
| Psoas muscle parameter (any) (continuous variable) | 10∗ | 0.88 (0.83-0.95) | 80.8% |
| PMI (dichotomous variable) | 6 | 2.32 (1.69-3.19) | 55.2% |
| TPMT (dichotomous variable) | 4 | 2.50 (1.48-4.23) | 52.5% |
| Sarcopenia (any definition) (dichotomous variable) | 11∗ | 2.29 (1.81-2.90) | 43% |
HR, hazard ratio; PMI, psoas muscle index; TPMT, transversal psoas muscle thickness.
∗
One study evaluated psoas muscle area.
