Abstract

A previously published randomized trial found a significant difference in the proportion of individuals experiencing oxalate reduction with a vitamin C with metabolites product compared with ascorbic acid (vitamin C). This represented a notable finding, which argued against the possibility of a chance finding due to the design and consistency of results. However, these researchers believed it was necessary to further analyze this study to continue to garner more insight on the strength or weakness of original findings. All favorable, neutral, and non-favorable changes of 24-hour oxalate from the previous clinical trial were grouped. Oxalate was considered to "decrease" or "increase" with each intervention only if a 10% or larger change occurred in the 24-hour oxalate baseline value when taking one product compared to another. A greater proportion of subjects taking both products at different time periods experienced favorable oxalate changes with vitamin C with metabolites product compared to ascorbic acid. If this reflects the true clinical scenario, this would represent an important clinical finding on a population level because at least 20% more individuals would experience a more favorable change. Regardless, this further analysis continues to suggest that the original observations were valid and could have positive clinical implications for some patients.
