Comparison of scores and immunohistochemical analysis. Correlation of histological grading and PRO_10 score. The 342 tumors were classified according to histological grading. The data are shown as boxplots with median (solid line), interquartile ranges (boxes) and minimum and maximum non-outlier values (whiskers). The PRO_10 scores higher and lower than the median are indicated as red and blue dots, respectively for each grade.
