Associations between phenol and paraben exposure and the risk of developing breast cancer in adult women: a cross-sectional study by Yao Xiong, Zhiyu Li, Xiong Xiong, Zixuan Luo, Kaixin Zhong, Jiawei Hu, Shengrong Sun, Chuang Chen

“…The results from the weighted multivariable regression models indicated that exposure to elevated concentrations of TRS increased the risk of developing BC by 2.33 (Q2: 95% CI = 1.45–3.75, p < 0.001) and 1.94 times (Q3: 95% CI = 1.21–3.09, p = 0.006), respectively. The nonlinear association between TRS concentrations and the risk of developing BC was statistically significant (P nonlinear = 0.007), with the restricted cubic splines (RCS) curve exhibiting an inverted U shape. …”
