Fig. 1From: Dual time point imaging in locally advanced head and neck cancer to assess residual nodal disease after chemoradiotherapyBoxplot of SUV70 measurements and RI of the whole study population and of visually equivocal patients. Top panel: boxplot of SUV70 measurements A and RI B of the whole study population (n = 102). Bottom panel: boxplot of SUV70 measurements C and RI D of visually equivocal patients (n = 24). 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 and asterisk indicate outliers and extreme outliers (beyond Q1 − 3*IQR or Q3 + 3*IQR), respectively. In panels B, C, and D, an extreme outlier was excluded to improve scalingBack to article page
