      Background Previous Mendelian randomization (MR) studies using population samples (population MR) have provided evidence for beneficial effects of educational attainment on health outcomes in adulthood. However, estimates ...
    • The effect of smoking intensity on all-cause and cause-specific mortality-a Mendelian randomization analysis. 

      Vie, Gunnhild Åberge; Wootton, Robyn E; Bjørngaard, Johan Håkon; Åsvold, Bjørn Olav; Taylor, AE; Gabrielsen, Maiken Elvestad; Davey, George Smith; Romundstad, Pål Richard; Munafo, Marcus R (Peer reviewed; Journal article, 2019)
      Background Smoking is an important cause of mortality and recent studies have suggested that even low-intensity smoking might be associated with increased mortality. Still, smoking is associated with lower socio-economic ...
