The middle horizontal bars represent the mean values and the upper and lower bars the respective maximum and minimum values. Wilcoxon matched pairs signed-rank test showed that Plan95^union had significantly higher TCP values than both Plan95^MRI and Plan95^PET, respectively (p < 0.05). Plan80^union only had significantly higher TCP values than Plan80^MRI (p < 0.05) but not than Plan80^PET (p = 0.5). There were no significant differences in TCP-histo values between Plan80/95^MRI and Plan80/95^PET (p = 0.371 for Plan80 and p = 0.844 for Plan95)
