Trial Outcomes & Findings for Magnetic Resonance Imaging in Subjects With Gouty Tophi (NCT NCT00174954)

NCT ID: NCT00174954

Last Updated: 2010-07-27

Results Overview

Two independent readers determined volume of the same tophus by MRI at 2 separate visits scheduled no more than 10 days apart. Difference in volume between Visit 1 and 2 for the same tophus was pooled across readers.

PRIMARY outcome

Timeframe: Visit 1 (Day 1) and Visit 2 (Days 6-11)

Population: Analysis was performed on the subjects with MRI tophus volume measurements at both visits from the same reader. Change in tophus size over 10 days was not expected.

Two independent readers determined volume of the same tophus by MRI at 2 separate visits scheduled no more than 10 days apart. Difference in volume between Visit 1 and 2 for the same tophus was pooled across readers.
