Estimated adjusted regression coefficients relating maternal prenatal urinary phthalate concentrations to the WISC-IV full scale IQ and subscales at child age 7 years.

*pp≤0.01. @Wald Test.Adjusted model for specific gravity, maternal IQ, ethnicity, alcohol use during pregnancy, education, marital status, total home score, and sex of child.Estimated adjusted regression coefficients relating maternal prenatal urinary phthalate concentrations to the WISC-IV full scale IQ and subscales at child age 7 years.

*pp≤0.01，采用Wald检验（Wald Test）。本研究构建了校正尿比重、母亲智商、种族、孕期饮酒情况、受教育程度、婚姻状况、家庭总评分以及子代性别等混杂因素的回归模型，并据此估算得到调整后的回归系数，用以揭示母亲孕期尿液邻苯二甲酸酯浓度与子代7岁时韦氏儿童智力量表第四版（WISC-IV）全量表智商及各分测验得分之间的关联。
