Table 2.

Average analysis metrics of passing samples depending on the observation of NUMT variants in the mtDNA data. The “% Mapped Reads” is the proportion of total reads that mapped to the GRCh37 and the “% mtDNA Reads” is the proportion of the mapped reads that aligned to the mitochondrial reference genome.

NUMT Variants	Count	Total Reads	% Reads Mapped	% Mapped mtDNA	Average Read Depth
None	561	869,724,465.0	99.17%	0.044%	2919.1
2–5%	265	854,695,905.9	99.16%	0.021%	1390.1
≥5%	91	855,009,718.4	99.16%	0.011%	686.1
