Ethnicity was known for 829/1,455 (57%) men. 781/1,455 (54%) men were white, 44/1,455 (3%) men were of ethnic minority, 121/1,455 (8%) preferred not to specify their ethnicity, and ethnicity data was missing for 507/1,455 (35%) men (Table 1). Mean follow-up time was 5.3 years and 183/1,455 men were lost to follow-up. Men who preferred not to disclose their ethnicity had significantly shorter follow-up time than those whose ethnicity was known or missing (p<0.001). Men who preferred not to disclose their ethnicity presented with higher risk cancers6 (p<0.001) higher Gleason grade, and were prescribed ADT for longer than other men (p<0.001). In our cohort, missing ethnicity data did not mean other data was missing.

There was no difference in overall survival between men of known ethnic groups (p=0.62, Figure 1A). However, overall survival was significantly worse for men who preferred not to disclose their ethnicity compared with men of known ethnicity and those with missing data (p=0.04, Figure 1B). This significance strengthened when considering only complete ethnicity data records (known vs prefer not to say) (p=0.015, Figure 1C).
