Fig. 1: Sequencing overview and fetal presence in pregnancy loss samples.
a, Flowchart of the study. b, The gestational ages of fetal samples. The gestational age was estimated as the time difference from the last menstruation to the date of pregnancy loss. c, The paternal fraction of fetal samples. The paternal fraction is shown for intervals of gestational age estimated on the basis of the last menstruation (GA–LM): weeks 0–9, weeks 9–12 and weeks 12–22. d, Kinship between fetal and parental samples. There are 26 (11 pregnancy loss cases) and 93 (59 pregnancy loss cases) fetal samples that had higher than expected kinship with their father and mother, respectively. Furthermore, there are 27 (11 pregnancy loss cases) and 42 (19 pregnancy loss cases) fetal samples from paternal and maternal triploidies, respectively.
