When cases were classified according to their ER and PR status combined, the HR for the highest vs lowest quintile of the ‘fruit and salad’ pattern were 0.92 (95% CI: 0.70–1.21; test for trend, P=0.5) for ER+ or PR+ tumours and 0.48 (95% CI: 0.26–0.86; test for trend, P=0.002) for ER− and PR− tumours (test for homogeneity by ER/PR, P=0.01). Here, PGR is linked to neoplasm.
