Table 2.

Item complexity. The rows are organized into three groups, based on our simple, intermediate, and complex mixture classification. In the left half of the table, the number of contributors is shown, arranged by total, known, and unknown contributor columns. The right half shows the number of inferred genotypes, giving the number having a TrueAllele match statistic, how many of those were reported by the human review laboratory with an associated match statistic, and the corresponding fraction of human to computer reporting (the computer always generated a match statistic when human review produced a statistic)
