Figure 1.

Swimmer plot showing patients and lesions evolution. ORR12w: overall response rate at 12 weeks after radiotherapy; CR, complete response; PD, progressive disease; PR, partial response. Horizontal bars represent each lesion (total number = 23). Each bar shows the length of follow‐up period for each treated lesion. Colors express overall response rate at 12 weeks (ORR12w) for each lesion. While geometrical shapes refer to patients (total number = 18) and are utilized to display additional information, including event of death, relapse of disease, or alive. In this context, for patients with multiple lesions, geometrical shapes will be just displayed in the first bar lesion (for instance, lesions 12, 13, and 14 refer to the same patient and thus event is only shown in the bar 12)
