Associations of the mixture of blood Pb and the essential metals with serum lipids profiles.

	Positive WQS regression	p	Negative WQS regression	p
TC	0.394 (0.265, 0.523)	<0.001	0.023 (−0.108, 0.154)	0.728
Ln TG	0.080 (0.015, 0.145)	0.016	0.019 (−0.038, 0.076)	0.510
LDL-C	0.369 (0.256, 0.482)	<0.001	0.060 (−0.044, 0.164)	0.263
HDL-C	0.071 (0.034, 0.108)	<0.001	0.013 (−0.024, 0.050)	0.503

Data are presented as the WQS regression index (95% CI), representing the overall mixture effect on serum lipids profiles. The model was adjusted for age, sex, education, smoking status, abused drink, BMI categories, hypertension and diabetes.

TC, total cholesterol; TG, triglyceride; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; WQS, weighted quantile sum.
