| Trios3 | 50.8a―44.8b | 78.8a―78.8a | 61.2a―56.6b |
| Sum of Squares | 3.408(143.092) | 14.308(46.122) | 87.363(191.065) |
| df | 1(27) | 1(27) | 1(27) |
| Median square | 3.408(5.300) | 14.308(1.708) | 87.363(7.076) |
| F | 0.643(−) | 8.376(−) | 12.345(−) |

Statistically significant at p < 0.05. Bonferroni: a>b. Repeated measures ANOVA group relations based on test pairwise comparisons are reported. The median trueness value used for statistical analysis showed no significant difference between Trios3-FDM and Ref-Trios3/FMD (p > 0.906) within the same column, and showed a significant difference between IOS-3DP and Ref-IOS/3DP (p < 0.001).
