Categorical variables were presented as n (%). Normally distributed continuous variables were depicted by Mean ± SD, and nonnormally distributed continuous variables were represented as Q2 (Q1, Q3). Q1: First quartile; Q2: Second quartile; Q3: Third quartile. PH, pregnancy history; WBC, white blood cell count; Hb, haemoglobin; PLT, platelet count; FIB: Fibrinogen, PT, prothrombin time; APTT, activated partial thromboplastin time; B-scan, B-scan ultrasonography; GAA, gestational age at amniocentesis; Chr, chromosome structure; GAD, gestational age at delivery; PO, pregnancy outcome; PTB, preterm birth; FS, foetal sex; BW, birth weight; D: Days, S, seconds.
