Increasing of PI Ox and PI Ca indicates that
oxalate and calcium salts are more easily soluble in the

whereas the PI Ca showed a statistically significant
difference between Day 0 and Day 2 although the
values of Day 5 and Day 8 were higher than Day 0. A
larger sample size would be needed to confirm this trend
