- Models were adjusted for maternal age at enrollment (ages), pre-pregnancy BMI (kg/m2), maternal education, paternal education, parity, per capita household income (< 4000, 4000–8000, and > 8000 CNY), maternal passive smoking (yes or no), maternal prenatal depressive symptoms (yes or no), and gestational age (weeks)
- aThe strong association may be caused by statistical imprecision mainly due to the imbalanced distribution of numbers of children having potential problems by PFOA concentrations. As shown in Table 5, there was no cases in the lowest tertile group of PFOA concentrations among girls, which potentially influenced the estimation in Poisson regression model
- ARR Adjusted risk ratio, CI Confidence interval
- * Statistically significant differences (p < 0.05)
