FIG 6. Graph (box plots) shows ADCs of metastatic nodes, nodal lymphomas, and nodes with benign lymphadenopathy. The horizontal line is a median (50th percentile) of the measured values, the top and bottom of the box represent 25th and 75th percentiles, respectively, and whiskers indicate the range from the largest to smallest observed data points within 1.5 interquartile range presented by the box. Note that ADCs of metastatic nodes are significantly higher than those of nodes with benign lymphadenopathy (P < .01, Mann-Whitney U test).
