Association of plasma Hsp70 with HRV by urinary PAHs metabolites in coke oven workers*.

1-OHNa, 1-hydroxynaphthalene; 1-OHP, 1-hydroxypyrene; 2-OHPh, 2-hydroxyphenanthrene; 9-OHPh, 9-hydroxyphenanthrene; ΣOH-PAHs, total concentration of all PAHs metabolites.*HRV indices were natural log transformed and presented as multivariate adjusted means and SE.aHsp70 tertile 1 through 3 were defined as less than or equal to 0.47 ng/ml, 0.47 to 1.52 ng/ml, and greater than 1.52 ng/ml, respectively. bMultivariate linear regression for the trend of HRV with Hsp70 levels with adjustment for age, sex, length of work, smoking status, alcohol use, BMI, physical activity, working sites, workshift and weekday. cGeneral linear models for the interaction between Hsp70 and PAHs metabolites on HRV. d1-OHP: Low≤2.20 μg/mmol creatinine, High>2.20 μg/mmol creatinine. e1-OHNa: Low≤1.09 μg/mmol creatinine, High>1.09 μg/mmol creatinine. fΣOH-PAHs: Low≤8.84 μg/mmol creatinine, High>8.84 μg/mmol creatinine. g2-OHPh: Low≤0.21 μg/mmol creatinine, High>0.21 μg/mmol creatinine. h9-OHPh: Low≤0.48 μg/mmol creatinine, High>0.48 μg/mmol creatinine.
