Figure 2

Box plots summarizing the distribution of the length (a) and width (b) values of the AB for samples A–C. Each box encloses 50% of the data with the median value of the variable displayed as a line. The top and bottom of the box mark the limits of ± 25% of the variable population (i.e. the Upper and Lower Quartiles, denoted as UpQ and LowQ, respectively). The lines extending from the top and bottom of each box mark the minimum and maximum values within the data set whose value is greater than UpQ + (1.5 Ă— DU-L) or less than LowQ − (1.5 Ă— DU-L), where DU-L is the distance between UpQ and LowQ. Any value outside of this range (outlier) is displayed as an individual point.
