A comparison of the infants’ treatment in the three groups [n (%)]
| Weight < 1000 g group (n = 11 cases) | Weight ≥ 1000~1250 g group (n = 32 cases) | Weight ≥ 1250~1500 g group (n = 64 cases) | t/χ 2 | P | |
|---|---|---|---|---|---|
| Noninvasive ventilation | 5 (45.45) | 18 (56.25) | 37 (57.81) | 0.58 | 0.75 |
| Noninvasive ventilation + Invasive ventilation | 3 (27.27) | 4 (12.5) | 11 (17.18) | 1.29 | 0.46 |
| Invasive ventilation | 2 (18.18) | 4 (12.5) | 2 (3.13) | 4.74 | 0.09 |
| PS for one time | 5 (45.45) | 17 (50.13) | 21 (32.81) | 3.80 | 0.17 |
| PS for twice or more | 2 (18.18) | 2 (6.25) | 8 (12.5) | 1.43 | 0.58 |
