  1. The tooth size errors were statistically different (p < 0.001) depending on the software used, and the post hoc test showed that DS (−0.019) > AS (−0.052) > LS (−0.121).
  2. DF degrees of freedom.
  3. F F value.
  4. ap values were derived from a generalised linear mixed model.
  5. bCategory (estimated mean) was presented for Bonferroni’s corrected post hoc test.
  6. cIntercept represents the mean value of the response variable when all predictor variables in the model are zero.
