Figure 1 : Salivary cortisol levels in endometriosis women.

(A). Women with endometriosis (n=31) have lower levels of salivary cortisol than health controls (n=36). Bars represent means and standard deviation.
(B). Using the Iterative Grubbs (alpha=0.05) two outliers were identified in the patients group. Comparisons were done using the Mann-Whitney non-parametric t-test. Statistical significance was set at p<0.05. *p=0.0195; **p=0.0033.
(C). Cortisol levels were not significantly different in women with endometriosis currently on or off hormone therapy (e.g., oral contraceptives, GnRH agonists, Depo-Provera). Hormone Therapy (Tx) n=16; No hormone Tx n=15. Bars represent means and standard deviation. Comparisons were done using the Mann-Whitney non-parametric t-tests. Outliers not eliminated. Statistical significance was set at p<0.05. p=0.9301.
(D). Cortisol levels had a tendency to be lower in women not currently receiving hormone therapy (e.g., oral contraceptives, GnRH agonists, Depo-Provera) compared to controls. Patients n=15; Controls n=15. Bars represent means and standard deviation. Comparisons were done using the Mann-Whitney non-parametric t-tests. Outliers not eliminated. Statistical significance was set at p<0.05. p=0.31.
