Top: Survival functions of the 60-patient data set estimated by our deep learning model, risk subgroups in this figure are the same as that in Figure 3. Bottom: Survival functions of 6 patients with negative circulating tumor cell measures and recurrence outcomes (false negative circulating tumor cells); the blue dash line represents the median survival function of patients in the low-risk group identified by our deep learning model.
