Fig. 2. The best response and tumor change in CNS during the follow-ups.
a Swimmer plot of the optimum response (PR/SD/PD) of each patient during the corresponding follow-up time (month). b Waterfall plot of tumor changes in CNS target lesion size. One patient had a stable disease, but the accurate tumor change was not evaluable due to the imaging examinations being conducted at a local hospital. PR partial response, PD progressive disease, SD stable disease.
