Abstract

Ca and P mg.% levels were directly related in all age groups of 650 individuals examined (r = + 0.402 [plus or minus] 0.033). The avg. ratio of Ca to P was 0.36 (standard deviation 0.12) with an observed range from 0.12-1.22 mg. %. The Ca-P ratio was highest between the ages of 20 and 29 yrs. and lowest in younger and older groups. The Ca-P product mg. % was lowest in the youngest age groups, while the mg./hr. product varied greatly and without relation to age.
