n = 62 for plasma and minerals in urine; n = 61 for fecal minerals; data are expressed as mean ± standard deviation; P1000/Ca0: 1000 mg phosphorus/0 mg calcium; P1000/Ca500: 1000 mg phosphorus/500 mg calcium; P1000/Ca1000: 1000 mg phosphorus/1000 mg calcium; ^{a b} mean values within a column with dissimilar superscript lower case letters are significantly different (p ≤ 0.05); * significant different to eight weeks within each group (p ≤ 0.05); effect of time was tested using general linear model with repeated measurements (with pairwise comparisons based on Bonferroni); fecal minerals were tested with paired and with unpaired Students t-Test within each intervention group and between intervention groups, respectively.
