Pre-assignment details
Of the 156 participants enrolled, 13 were initially assigned to an active control group (Febuxostat) under the original protocol. This group was removed following a protocol amendment. Final results are reported based on the amended protocol, which excluded the active control group. Therefore, the discrepancy between the total number randomized and the final reported number reflects this change.
