n = 56; data are expressed as mean (standard deviation); CaP: tricalcium phosphate; a b mean values within a row with dissimilar superscript letters are significantly different (p ≤ 0.05); 1 2 mean values within a column with dissimilar superscript numbers are significantly different (p ≤ 0.05); results without superscripts in a row/column have no significant differences; effect of time was tested using general linear model with repeated measurements (with pairwise comparisons based on Fishers-LSD test); effect of supplementation was tested using univariate analysis of variance followed by Student-Newman-Keuls post hoc test.; t for statistical analysis the data were log10 transformed, because of variance heterogeneity.
