Results
Using the morphological assessment,
all SMs were attributed to the correct saw type (i.e.,
28 SMs each) (Fig 3).
Concerning the quantitative assessment,
saw1_8TPI and saw1_11TPI showed statistically significant differences for the angles and the mean between the angles (p<0.001; 100% accuracy,
each) (Table 1).
KW allowed a perfect distinction between saw2_8TPI and saw2_10TPI (i.e.,
p<0.001; 100% accuracy) (Table 2).
No differences occurred between saw3_18TPI and saw3_24TPI for any metric (Table 3).
Thus,
our results demonstrated that a morphometric flow-chart,
based on the morphologic and quantitative assessments of saw marks on bone,
allow a precise morphological identification of the saws,
and demonstrated that specific metrics even enable the distinction of saws of the same type differing only for TPI (Fig 4).
