Table 3 Ultrasound assessment of diaphragm function in frail and non-frail elderly patients. Includes end-inspiratory and end-expiratory diaphragm thickness, diaphragm excursion during deep breathing, and diaphragm thickness fraction (DTF).
| Laboratory index | Non-frailty group (n=36) | Frailty group (n=117) | t/χ2 | P |
|---|---|---|---|---|

| End-inspiratory diaphragm thickness | 0.24±0.08 | 0.25±0.06 | 0.805 | >0.05 |
| End-expiratory diaphragm thickness | 0.18±0.04 | 0.15±0.09 | 1.938 | >0.05 |
| Diaphragm thickness fraction (%) | 74.31±6.25 | 68.12±5.42 | 5.775 | <0.05 |
