Sex differences in the impact of image-based parameters on survival [31]. The differences between the connections of the red and blue ribbons represent sex differences in the prognostic significance of image-based tumor and patient characteristics. The bottom portion of the outer ring lists the relevant quantitative variables and the top portion shows the three aspects of survival that are associated with these variables (EXS, STS, and Overall Survival). Red ribbons indicate significant relationships for female patients between the parameter and the survival group and blue ribbons indicate significant relationships for male patients. Variables that were significant in multivariate CPH are connected to the Overall Survival segment and variables that were significant in Student t-tests with Welch’s correction are connected to the relevant EXS or STS segments
