Figure 2:

Evaluation of the site differences in PRM measurements. Box and whisker plots are presented for the relative volume of PRM-derived measurements from paired CT scans acquired at each site. The line within the box, the box extremes and whiskers represent the median value, 25%ile and 75%ile, and 5%ile and 95%ile, respectively. Markers represent outlies beyond 5%ile and 95%ile. Site differences in variables were tested using a univariable ANOVA controlling for multiple comparisons using the Bonferonni posthoc test. Significance was assessed at a p-value of 0.05. No significant differences were observed between sites for the presented measurements.
