Sex Determination Using Inion-Opistocranium-Asterion (IOA) Triangle in Nigerians’ Skulls

Table 2

Maximum, minimum, geometric mean, coefficient of variation, mean, and SEM of left opistocranium-asterion length and right opistocranium-asterion length (mm).

Sex	Mean ± SEM	Coefficient of variation	Geometric mean	Maximum	Minimum
Male (mm)	71.09±0.56	7.50%	70.88	82.95	52.51
	(69.73±0.49)^#	(6.67%)	(69.58)	(81.79)	(57.71)
Female (mm)	61.68±3.35^∗	16.28%	60.90	74.10	44.00
	(60.92±2.10^∗)^#	(14.53%)	(60.35)	(75.00)	(48.00)

^∗𝑃<0.05 statistically significant. Numbers in brackets represent right opistocranium-asterion length (mm)^#.
