MeanRR (a), SDNN (b), rMSSD (c) and PNN50 (d) according to ZnO concentrations and time points. Differences between before exposures and the different time points with a significance level of p < 0.05 are indicated. A significance level of α = 0.0031 resulted after Bonferroni correction. Outliers (dots) are defined as values above median + 1.5 x interquartile range or values below median - 1.5 x interquartile range
