Fig. 2From: Dual time point imaging in locally advanced head and neck cancer to assess residual nodal disease after chemoradiotherapyBoxplot of SUV70 measurements and RI in HPV-negative and HPV-associated OPSCC. Top panel: Boxplot of SUV70 measurements A and RI B in HPV-negative OPSCC. Bottom panel: Boxplots of SUV70 measurements C and RI D of HPV-associated OPSCC. The boxes represent the interquartile range, and the horizontal line represents the median. The whiskers represent the minimal (Q1 − 1.5*IQR) and maximal (Q3 + 1.5*IQR) values. The dots represent outliers. In panel D, two extreme outliers were excluded to improve scalingBack to article page
