Maternal organ damage except thrombocytopenia^b	23 (12.2)	6 (11.8)	13 (54.2)	1.000	< 0.001	< 0.001

^a: mean ± standard deviation, statistical significance was calculated with analysis of variance and multiple comparison was conducted with Bonferroni method
^b: n (%), statistical significance was calculated with Fisher’s exact test and multiple comparison was conducted with Hochberg method
Normal, platelet count ≥ 150 × 10⁹/L; Mild, platelet count < 150 × 10⁹/L and ≥ 100 × 10⁹/L; Severe, < 100 × 10⁹/L
P1, normal versus mild; P2, normal versus severe, P3, mild versus severe
