title: [Comparison of results for evaluating calcium and phosphorus content in children's daily diets obtained by analytical methods and calculations].
abstract: The results of two methods for the estimation of calcium and phosphorus in daily rations of children aged up to 1 year were compared by simple statistical tests. Ca and P contents were determined by the analytical method; moreover, the theoretical Ca and P contents were calculated from the bills of fare menus and food composition tables. The analytical procedure was accepted as reference method. Ca and P contents determined by the analytical method accounted, on the average, for ca. 90% of those obtained by the calculation method. The coefficients of correlation between the results obtained by both methods (x and y) amounted to: rCa = 0.456 and rP = 0.786. There were significant differences between Ca and P contents obtained by both methods at significance level alpha = 0.05.
