WQS model to estimate associations between WQS index and uterine leiomyomata and endometriosis.

Outcomes	OR (95% CI)	P value
b1_positive
Uterine leiomyomata	2.54 (1.52, 4.29)	<0.001
Endometriosis	2.01 (0.98, 4.15)	0.058
b1_negative
Uterine leiomyomata	0.70 (0.39, 1.24)	0.222
Endometriosis	0.51 (0.25, 1.05)	0.067

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, menopause status, and log-transformed urinary creatinine levels.
