Frequency analysis of all samples included (n = 150) and comparison between Europeans (E) and Japanese (J)

	Anteversion				Inclination
	Average		Left/right		Average		Left/right
	E n = 100	J n = 50	E n = 100	J n = 50	E n = 100	J n = 50	E n = 100	J n = 50
Median	29.8°	21.6°	29.1°/29.0°	19.4°/22.5°	51.8°	49.9°	50.7°/52.3°	49.6°/49.5°
SD	9.08	6.97	9.02/9.73	7.08/7.49	3.79	3.32	4.05/4.22	3.5/3.83

p‐value (α = 0.05)	<0.0001				0.0088

Note: Anteversion and inclination were significantly higher in Europeans than in Japanese individuals.

Abbreviation: SD, standard deviation.
