CCL4 (C─C motif ligands 4, Beta = 0.015, 95% CI: 0.001–0.030, p=0.049), DNER (Beta = −0.025, 95% CI: −0.045 to −0.005, p=0.013), IL15RA (interleukin 15 receptor subunit alpha, Beta = 0.014, 95% CI: 0.003–0.026, p=0.016), LIFR (Beta = 0.046, 95% CI: 0.014–0.079, p=0.005), SCF (stem cell factor, Beta = 0.021, 95% CI: 0.002–0.040, p=0.033), TGFA (Transforming growth factor alpha, Beta = 0.037, 95% CI: 0.008–0.066, p=0.011), VEGFA (vascular endothelial growth factor A) (TGFA, Beta = −0.010, 95% CI: −0.019 to −0.002, p=0.021) were causally associated with HB. Here, DNER is linked to hemoglobin measurement.
