Population features between the Normal group and SGA group
| Normal group | SGA group | P | |
|---|---|---|---|
| Number | 101 | 10 | |
| Maternal age (years) | 34.4 (±5.6) | 33.6 (±4.7) | NS |
| Gravidity | 0.9 (±1.2) | 1.3 (±1.3) | NS |
| Parity | 0.5 (±0.9) | 0.6 (±0.7) | NS |
| Gestational age (weeks) | 31.7 (±6.3) | 32.8 (±4.2) | NS |
| EFW (SD) | +0.11 (±0.74) | -2.33 (±0.84) | P<0.01 |
| Placental Index | 8.8 (±10.0) | 44.3 (±29.4) | P<0.01 |
| HT score | 1.56 (±0.68) | 2.70 (±0.67) | P<0.01 |
| Birth weight (SD) | 0.11 (±1.13) | -2.19 (±1.07) | P<0.01 |
| Placenta weight (g) | 562.3 (±119.7) | 366 (±120.0) | P<0.01 |
The above values represent the mean (standard deviation).
EFW = estimated fetal weight; HT = score hardness of tissue score; SGA = small for gestational age
