Demographic Characteristics
| Variables | ROP | Non-ROP | P Value |
|---|---|---|---|
| Gestational age (weeks) | 31.20 ± 4.62 | 30.96 ± 4.17 | 0.657 |
| Birth weight (kg) | 1.263 ± 0.345 | 1.220 ± 0. 293 | 0.546 |
| Delivery mode (cesarean section %) | 12 (32.40) | 19 (65.50) | 0.008* |
| Multiple pregnancy (singleton %) | 18 (48.60) | 21 (70.00) | 0.078 |
| Sex (male %) | 15 (38.50) | 30 (73.20) | 0.002* |
| Feeding strategy (TPN and nontrophic feeding %) | 32 (80.00) | 39 (95.12) | 0.084 |
| TPN (mL) | 105.4 ± 25 | 103.2 ± 27 | 0.707 |
| Breast milk (mL) | 8.0 | 8.0 | 0.970 |
| Oxygen saturations (%) | 92.5 | 92.5 | 0.291 |
| FiO2 (%) | 30 | 29 | 0.724 |
Numbers were expressed as mean ± SD. Gestational age, birth weight, and TPN are normally distributed parameters whose significant differences (P value) are calculated using Student's t-test. Breast milk, oxygen saturation, and FiO2 are presented by median and statistical significance analyzed using Wilcoxon rank-sum test. Delivery mode, multiple pregnancy status, sex, and feeding strategy are analyzed by Chi-squared test. TPN = total parenteral nutrition.
