Fig. 6: Association between BMI, age, alcohol drinking and smoking and individuals to be genetically variable across blood cell traits in INTERVAL.

a An overall Z score test estimate across 27 blood cell traits. b Z score test estimates for mean corpuscular volume (mcv), neutrophil percentage of white cells (neut_p) and red blood cell count (rbc) which were significant Mendelian Randomisation analyses. Z score = beta (effects) / se (standard error). * (nominal 2-sided): p < 0.05; **: p < 0.01; ***: p < 0.001 and **** p < 0.0001.
