The effect of cffDNA enrichment. a Foldchange of cffDNA fraction in 10 different bins, including [100, 110), [110, 120), [120, 130), [130, 140), [140, 150), [150, 160), [160, 170), [170, 180), [180, 190), [190, 200), calculated using reads portion of the Y chromosome. b Alteration of read length distribution after size-selection using our customized beads with different dosages. c The portion of short reads (< 160) increased after size-selection using our customized beads with different dosages. d The Z-score of ChrY increased after size-selection using our customized beads with different dosages
