Figure 3

Boxplots representing the tooth lengths of incisors in different Triadan positions. a: upper jaw incisors. b: lower jaw incisor. Triadan position assigned to the tooth length. Box: interquartile range (25%, 75%), horizontal line: median, center point: mean, whiskers: range (5%, 95%), stars: minimum and maximum. Lower-case characters (a, b) indicate a significant difference. (p-values upper jaw incisors: Triadan 01 against 02: p = 0.038, Triadan 01 against 03: p = 0.54, Triadan 02 against 03: p = 0.0019; p-values lower jaw incisors: Triadan 01 against 02: p = 0.16, Triadan 01 against 03: p = 0.007, Triadan 02 against 03: p = 0.32).
