Fig. 4From: Time-varying associations between prenatal metal mixtures and rapid visual processing in childrenPlot showing the relationship between RVP accuracy and the (a) JWQS and (b) MWQS indices. Both plots are locally estimated scatterplot smoothing (LOESS) plots. The individual points in both plots are residuals accounting for the covariates: child age, child gender, maternal socio-economic status and age of the mother at recruitment. The WQS index estimated using JWQS was significantly and nonlinearly associated with the accuracy in the RVP (β [95%CI], p-value: − 0.41 [− 0.79, − 0.03], p < 0.05) for the linear term and (0.05 [0.00, 0.09], p < 0.05). The WQS index estimated using MWQS was marginally and nonlinearly associated with the accuracy in the RVP (− 0.12 ([− 0.26, 0.01], p < 0.10) for the linear term and (0.01 [− 0.00, 0.03], p < 0.10) for the quadratic term.
