a, Protein levels by blood group and secretor status for four proteins with the most significant interaction effects. The box plots show the median (centre line), first and third quartiles (box limits), and 1.5× the interquartile range above and below the third and first quartiles (upper and lower whiskers). n = 52,363 independent samples. b, Enrichment of genes encoding proteins with significant interactions (P < 1.7 × 10−5) for expression in various human (left) and mouse (right) tissues. The numbers above the bars represent unadjusted P values calculated using one-sided hypergeometric enrichment tests; the blue bars indicate significance after multiple-testing correction. E14.5, embryonic day 14.5.
