Figure 2:

Illustration of treatment changes in SEER-Medicare data of women with confirmed endometrial cancer. In these data, once someone is treated, she is considered a treated patient for the remainder of the time on study. During each month, a subgroup of untreated individuals go on to receive chemotherapy (CT) and/or radiation (RT). Other subgroups of individuals having previously received one treatment go on to receive the other (RT + CT). Darker shading is used to denote higher relative frequency within a particular month.
