Relation between baseline and ACTH-induced increases in cortisol/albumin and SAPS II score. (a) Association between baseline cortisol/albumin and Simplified Acute Physiology Score (SAPS) II score (five strata; P < 0.0001, Kruskal-Wallis test). (b) Association between adrenocorticotrophic hormone (ACTH)-induced increases in cortisol/albumin and SAPS II strata (P = 0.002, Kruskal-Wallis test).
