Fig. 3 — Event-free survival (EFS) deviated significantly from the original cohort for both synthetic cohorts (a). For the NFlow-generated cohort, there was no significant deviation from the original distribution for overall survival (OS), while the CTAB-GAN + -generated cohort again differed significantly (b). Interestingly, while the survival curve for CTAB-GAN+ displays a plausible curve up until ten years of follow-up, the curve shows no stabilization of survival rates in the end as the original cohort does. Contrastingly, the survival curve for NFlow shows an overall plausible course, however, NFlow tends to overtly censor patients after two years of follow-up.
