(a) The total number of skulls was not necessarily measured in the variables presented in the article, that is, there was a confusion bias.

(b) The methodology describes a number of 16 skulls studied, however, the measurements do not make a statistically significant distinction between the male and female sex.

(c) Measurement was made in the "mid-sagittal" plane.

(d) Based on the statistical analysis of Kranioti et al (2008).

(e) Maximum distance between the anterior and posterior margins measured along the main axis of the foramen magnum

(f) Length of the foramen magnum without detailed anatomical references in the methodology.

(g) Based on data collection from Ulcay et al (2021).
