Fig. 3From: Per- and polyfluoroalkyl substances (PFAS) and neurobehavioral function and cognition in adolescents (2010–2011) and elderly people (2014): results from the Flanders Environment and Health Studies (FLEHS)Forest plot of the estimates of outcomes of the neurocognitive tests (NES3 tests, Stroop test) in relation to the measured PFAS in the different FLEHS studies (with FL2 = FLEHS-2, FL3 = FLEHS-3, ADO = adolescents, ADU = adults).). The estimate (95% confidence interval) is expressed for an interquartile increase in exposure (calculations on ln-transformed effect marker values). Confounders and covariates that were included at the start of the stepwise multiple regressions are mentioned in Additional file 1 Tables S1 and S2Back to article page
