Effects of 2-years of supplementation with vitamin K2 (MK-7, 360 μg daily) or placebo: Bone mineral density. Mixed effect model analysis of changes in bone mineral density. (A) Lumbar spine (n = 119_baseline, 92_{year 1} and 62_{year 2}). (B) Femoral neck (n = 118_baseline, 91_{year 1} and 60_{year 2}). (C) Whole body (n = 105_baseline, 80_{year 1} and 55_{year 2}). Variables are unadjusted and presented as mean and 95% confidence intervals (CI). Significant between group differences *: P ≤ 0.005. BMD, bone mineral density.
