Comparison of quantitative parameters estimated by 3K model in primary lung cancers and metastatic lymph nodes. Box plot of mean values (top row) and standard deviation (SD, bottom row) of Ki, K1 and Vb, respectively, in primary lung cancers (n = 23) and metastatic lymph nodes (n = 24). The individual values making up the box plot are shown as grey points. In the box plots, the red line indicates the median value and the edges of the box plot are the 25th and 75th percentiles, whereas the star (*) indicates statistically significant differences between the two groups (p < 0.05, Wilcoxon rank-sum test)
