Violin plots for the 101 evaluated mask batches with 993 individual measurements. The dashed lines indicate the limit according to DIN EN 149. All measurements and the data evaluation were done according to DIN EN 149 and DIN EN 13274-7. The gray background indicates a change in scale in the y-axis. An extensive explanation of violin plots can be found in the “Materials and methods” section. : median, : kernel density plot, : interquartile range (boxplot from upper to lower quartiles), | minimum to maximum value excluding outliers.
