IL7R and urinary bladder cancer: Though categorised as suggestive evidence, the strongest associations observed in this group were for tumour necrosis factor ligand superfamily member 10 (TRAIL) concentrations and breast cancer risk (OR 0.90 per SD increase, 95% CI 0.85–0.95, q-value = 0.072), circulating macrophage migration inhibitory factor (MIF) concentrations and bladder cancer risk (OR 2.46, 95% CI 1.48–4.10, q-value = 0.072), and interleukin-7 receptor subunit alpha concentrations and colon cancer risk (OR 0.83, 95% CI 0.74–0.93, q-value = 0.093).
