Embryonic miRNA Profiles of Normal and Ectopic Pregnancies - Table 2

The patient characteristics for the samples used for the real time PCR analysis. Data is presented as the mean plus or minus (±) the standard error mean (SEM) or as the number and its corresponding percentage; ns  =  not significant. Gestational age (in days), gravidity, the number of births, history of previous spontaneous or induced abortions, and the number of induced abortions were evaluated with the Mann–Whitney U test while any history of previous ectopic pregnancies, abdominal or pelvic surgeries, infertility, or use of IUD or progestogen contraception was evaluated using Fisher's exact test.

本数据集对应用于实时荧光定量PCR（real-time PCR）分析的样本的患者特征。数据以均值±标准误（standard error mean, SEM）形式呈现，或以例数及其对应百分比形式呈现；ns 表示无统计学意义。针对妊娠天数、孕次、分娩次数、既往自然流产或人工流产史以及人工流产次数，采用曼-惠特尼U检验（Mann–Whitney U test）进行统计分析；而对于既往异位妊娠史、腹部或盆腔手术史、不孕症史，以及宫内节育器（IUD）或孕激素避孕方式的使用史，则采用费舍尔精确检验（Fisher's exact test）进行统计分析。
