Peak cortisol response to CRH stimulation by weight quartile over the entire cohort. N = 222 (quartile 1: n = 57, quartile 2: n = 54, quartile 3: n = 56, quartile 4: n = 55). Dotted line represents a commonly used threshold for stimulation test failure, cortisol of 500 nmol/L. ** p-value = 0.003 for quartile 4 vs quartile 1 after Bonferroni correction
