Fig. 2. (A ) Correlation between baseline total and free cortisol concentrations in brain-dead patients with low (dotted line , n = 25, r²= 0.73, P < 0.001) or normal albumin (solid line , n = 17, r²= 0.89, P < 0.01) concentration. (B ) Correlation between baseline total and free cortisol concentrations in brain-dead patients with low (dotted line , n = 16, r²= 0.97, P < 0.001) or normal corticosteroid-binding globulin (solid line , n = 26, r²= 0.89, P < 0.01) concentration. Alb = albumin; CBG = corticosteroid-binding globulin.
