From: Neurobehavioral effects of transportation noise in primary schoolchildren: a cross-sectional study
The relation between road traffic noise exposure (L Aeq, 7-23 hrs ) and the scores on the NES tests adjusted for confounders. The dotted vertical line corresponds to no effect of road traffic noise exposure. The circles correspond to the estimated change in Z-score per 5 dB(A) increase of the road traffic noise level and the horizontal lines correspond to the 95% confidence interval.
