Age 36–40	−26.838 (11.073; −48.635)	11.073	0.016	69 (25.8)
Age 41–45	−38.752 (10.920; −60.247)	10.920	<0.0001	94 (35.3)

Age 51–55	−58.336 (12.112; −82.178)	12.112	<0.0001	162 (60.5)
Age 56–60	−69.109 (15.241; −99.109)	15.241	<0.0001	167 (62.5)

A negative beta indicates a decline of DHEAS with increasing age.

^aAll adult females (n = 268). Percent (number of cases <2040 nmol/L divided by 268).
