PGR and neoplasm: The fully adjusted logistic regression showed that ER+ tumours were inversely associated with SBR grade II (OR = 0·21, P<0·001), grade III (OR = 0·06, P<0·001) and HER+ (OR = 0·54, P = 0·007), and positively associated with age (OR = 1·02, P = 0·008), PR+ (OR = 16·64, P<0·001), and CCI score≥1 (OR = 1·91, P<0·048).
