Maternal and fetal outcomes.

AGA, appropriate for gestational age; GA, gestational age; SGA, small for gestational age; LGA, large for gestational age.Data are summarized as mean ± standard deviation or % (n) values.**Data are presented as median (IQR) values. Data were analyzed using Wilcoxon rank-sum test.†P value, Student’s t-test.‡P value, chi-square test.¶P value, Fisher’s exact test.

AGA（appropriate for gestational age，适于胎龄儿）、GA（gestational age，胎龄）、SGA（small for gestational age，小于胎龄儿）与LGA（large for gestational age，大于胎龄儿）。数据以均值±标准差或百分比（例数）形式汇总。**数据以中位数（四分位数间距，IQR）形式呈现。数据分析采用Wilcoxon秩和检验。†P值对应Student t检验；‡P值对应卡方检验；¶P值对应Fisher确切概率法。
