Comparison of clinical data for neonates. a. The birth weight of neonates distributed in the five groups showed no statistical difference (P = 0.183); b. There was no statistically difference between the number of boys and girls in the five groups (P > 0.5). c. In terms of gestational age, neither for small gestationalage (SGA) (P = 0.759) nor for large gestationalage (LGA) (P = 0.791) showed significant differences between the five groups. However, the proportion of LGA was much higher than that of SGA in total neonates (^●p < 0.05); d. The incidence of macrosomia was not significantly different between the five groups (P > 0.5). Notes:A, solid food ≥8 h and clear fluids ≥6 h; B, solid food ≥8 h and clear fluids ≥2 h < 6 h; C, solid food ≥6 h < 8 h and clear fluids < 2 h; D, solid food ≥2 h < 6 h and clear fluids < 2 h; E, solid food < 2 h and clear fluids < 2 h
