From: Inferring fetal fractions from read heterozygosity empowers the noninvasive prenatal screening
Performance of fetal fraction (FF) inference in clinical noninvasive prenatal screening (NIPS) samples. For each sample (represented by a dot), FFs estimated from sex chromosomes are on the x-axis and FFs estimated from read heterozygosity are on the y-axis. Dots marked in red (23/443) are twin pregnancies after in vitro fertilization (IVF). Samples with female fetuses are marked in gray, and samples with male fetuses are marked in black. The gray diagonal line is y = x and the blue line is y = 2x.
