Influence of Environmental Factors and Relationships between Vanadium, Chromium, and Calcium in Human Bone

Table 3

The concentrations of V, Cr, and Ca in the cartilage, cortical bone, and spongy bone in women and men with osteoarthritis (AM, arithmetic mean; SD, standard deviation; Med, median, CV, coefficient of variation in percent; , Mann-Whitney test; , level of significance; and NS, nonsignificant difference; V and Cr concentrations are expressed as mg/kg dm; Ca level is expressed as g/kg dm).
