Mean Cortisol at Each Time of Day

Cortisol Units	Group	M1 (SD)	M2 (SD)	A (SD)	E (SD)	Total (SD)
ng/mL	ASD	2.86(1.20)	3.58 (1.60)	1.40 (1.73)	0.47 (0.59)	2.09 (0.85)
ng/mL	TD	2.54(1.11)	3.23 (1.46)	0.83 (0.35)	0.18 (0.14)	1.69 (0.59)

Log₁₀ (ng/mL)	ASD	0.38 (0.19)	0.47 (0.24)	−0.10 (0.34)	−0.68 (0.45)	0.03 (0.21)
Log₁₀ (ng/mL)	TD	0.33 (0.23)	0.44 (0.22)	−0.17 (0.22)	−0.92 (0.31)	−0.08 (0.17)

Note. ASD n =36; TD n = 27; Cortisol values at teach time of day (M1=Immediately upon waking, M2=30 minutes post-waking, A= Afternoon, approximately 3pm; and E=Evening, 30 minutes before bedtime), averaged across three days. Total cortisol was calculated as the average of the four times of day.
