Relationships between within-session cocaine intake and plasma CORT and PRL determined from blood obtained immediately after the 10-h SA sessions

Postsession Plasma	Relationship (r Value) to Within-Session Cocaine Intake
Postsession Plasma	All Days	SA Day 1	SA Day 2	SA Day 3	SA Day 4	SA Day 5
CORT (ng/ml)	0.505^3-a F = 70.22	0.595^3-a F = 22.41	0.569^3-a F = 19.64	0.589^3-a F = 20.67	0.393^3-a F = 6.92	0.305 F = 3.90
PRL (ng/ml)	−0.077F = 1.14	−0.507^3-b F = 13.11	−0.147 F = 0.82	−0.015F = 0.01	0.106 F = 0.39	0.080F = 0.24

Data represent the correlation coefficients (r values) and the corresponding F values determined using linear regression analyses.
