Means (standard deviation) and report rate of the variables used in the study.

| C1 (ng/mL) | 5.80 (3.04) | 6.44 (3.18) | 5.18 (2.80) | 0.029 |
| GSST cortisol | ||||
| C2 (ng/mL) | 4.79 (2.40) | 4.80 (1.58) | 4.26 (1.73) | >0.05 |
| C3 (ng/mL) | 6.51 (3.13) | 8.31 (2.29) | 5.96 (1.75) | <0.001 |

C1 = baseline cortisol; C2 = before GSST; C3 = cortisol concentration at the end of the GSST; C4 = cortisol concentration 20 min after the end of the GSST; C5 = cortisol concentration 40 min after the end of the GSST; AUCi = area under the curve with respect to the increase.
