Fig. 2

Figure shows among women receiving chemotherapy, how use of adjuvant and neoadjuvant chemotherapy has changed over time, relative to hormone receptor status and HER2 status. Note that in this graph, negative hormone receptor status refers to ER (estrogen receptor)- and progesterone receptor (PR) - disease, while hormone receptor positive status reflects ER+ and/or PR+ disease. Figure also shows the group who received chemotherapy but for whom there's no indication of receipt of surgery or for whom surgery data are missing, and thus are grouped separately
