WQS model to estimate the association between WQS index and uterine leiomyomata and endometriosis in premenopausal participants (N=1045).

Outcomes	OR (95% CI)	P value
b1_positive
Uterine leiomyomata	2.34 (1.22, 4.57)	0.011
Endometriosis	2.18 (1.03, 4.70)	0.043
b1_negative
Uterine leiomyomata	0.64 (0.33, 1.22)	0.177
Endometriosis	0.46 (0.19, 1.09)	0.079

OR, odds ratio; CI, confidence interval. OR estimation represents the odds ratios of uterine leiomyomata or endometriosis as one tertile increased in the WQS index. The positive and negative association was estimated respectively. Models were adjusted for age, ethnicity, BMI group, ovary removal, female hormone usage, pregnant status, and log-transformed urinary creatinine levels.
