Statistical analyses
The effects of oAC treatment on serum phosphate, serum calciumphosphate
product, iPTH and 1,25-dihydroxyvitamin D were analyzed
using the changes from baseline to the end of the treatment
period. Safety was estimated based on the frequency of adverse events and changes in laboratory results. All statistical analyses were
performed using SPSS 16.0 software. Data were expressed as
mean 1 standard deviation (SD). The effects of oAC on the serum
phosphate levels and other laboratory parameters were assessed
using one-way analysis of variance (ANOVA), the difference between
groups were determined using least significant difference (LSD) and
Student Newman Keuls tests. A P-value of less than 0.05 was considered
statistically significant.
