ANOVA test. All pairwise multiple comparison (Tukey test). *All pairwise multiple comparison (Dunn test). Nomenclature: DR, dorsal rootlets; rWB, root width from bone; rRA, rostral root angle; cRA, caudal root angle; rR, rostral root length; cR, caudal root length; DC, width across dorsal columns; rR-cR, rostral root to caudal root length. ND, No statistical differences were found.
