Stage I tests based on Landmark distance (LMD) data.

p values lower than 0.1 were marked in bold. The abbreviation for landmarks: Left external canthus (LExtCan); Left internal canthus (LIntCan); Right internal canthus (RIntCan); Right external canthus (RExtCan); Pronasale (Prn); Nasion point (Nsn); Left Alare (LAla); Right Alare (RAla); Subnasale (Sbn); Right lip corner (RLipCn); Left lip corner (LLipCn); Lip center (Stm); Upper lip point (ULipP); Lower lip point (LLipP); Chin point (ChiP). For each LMD comparison, the first row is the raw Tukey p value, and the second row is the p value corrected by permutation. All the comparisons with raw p value below 0.01 were listed. The permutation
