Fig. 5From: Preselection of robust radiomic features does not improve outcome modelling in non-small cell lung cancer based on clinical routine FDG-PET imagingPatient stratification based on 12-month EFS. Patient stratification into high risk (light grey, interrupted lines, 95%-CI in light grey) and low risk (dark grey, solid lines, 95%-CI in dark grey) was significant for 12-month EFS: a training cohort, p value = 0.03 and b validation cohort, p value = 0.02Back to article page
